dbace0b2fa Cleaned up the disgusting mess that was the list of frames. The changes:
- removed root_frame. "frames" now takes its place.
- removed frame->prev. In those few cases where we need the previous frame (for
  deletion and dumping), we walk the list or recurse.
- the list of frames is now in GUI order, not file order.
- when reading the .fpd file, put the root frame first and leave it there.
- instead of walking the frames list and excluding the root frame by testing
  frame->name, just start at frames->next
- likewise, instead of testing !frame->name just use frame == frames

e047cc074d Holes can now also be output as KiCad modules.
- gui_style.c (gc_rim): slightly increased brightness when inactive
- kicad.c (kicad_pad): move coordinate transform to new function kicad_centric
- kicad.c: added pads with holes and mechanical holes
- inst.h (struct inst.u.hole), inst.c (inst_hole): added "layers" field, like 
  for pads
- layer.c (LAYER_COPPER, LAYER_PASTE, LAYER_MASK): renamed to LAYER_*_TOP and
  added macros for corresponding bottom layers
- layer.c (refine_layers): mirror top layers of through-hole pads
- layer.h, layer.c (mech_hole_layers): return the layer set for mechanical 
  layers

1dda2ac2ae When creating an object in the GUI, its label wasn't initialized. Added
infrastructure for hole objects. (Postscript and KiCad output are still 
missing, and so does sanity checking.)

- gui_tool.c (new_obj_unconnected): set obj->name to NULL
- added hole objects to tool bar, all the various GUI routines, the .fpd
  parser, and the .fpd dumper

6b22c8a579 The characteristics of the diagonal of the object selected (length and angle)
were taken from the bounding box and thus included silk width and other
confusing things.

- inst.c (rect_status_sort): wrapper for rect_status that sorts the coordinates
  (min/max)
- inst.c (line_op_select, rect_op_select, meas_op_select): display the
  characteristics of the diagonal of the ideal line(s), not of the bounding box
- inst.c (pad_op_select, rpad_op_select): normalize the diagonal by using
  rect_status_sort instead of rect_status. This makes pads behave like silk
  screen objects.

6374b3a61a Added debugging directives to the fped language. They're describe at the end
of README.

- fpd.l, fpd.y, README: added debugging directives %del, %move, %print, %dump,
  and %exit
- obj.h, fpd.y (find_obj, find_label, new_obj): objects can now be labeled
- obj.c (obj_anchors), inst.c (inst_anchors): gathering the list of anchors is 
  now a per-object function, not an instance "method". inst_anchors implements 
  the vector vs. object switch.
- inst.h, inst.c: removed all *_op_anchors functions
- expr.c (str_unit): in the past, we returned a malloc'ed string, but these 
  times are long gone. Thus, don't stralloc("").

3d6ef48930 As a shortcut, accept entry of "0" as a valid distance for dimensions. (For
safety, this only works if used directly, not through variables.)

- gui_status.c (edit_any_expr): replaced with dist_expr_store, which changes
  values of "0" to "0mm"
- gui_status.c, gui_status.h (edit_dist_expr): new function to edit distance
  expressions
- inst.c (obj_line_edit, obj_rect_edit, obj_arc_edit, obj_meas_edit): changed
  edit_expr to edit_dist_expr

8a0039f202 When clicking on an instance, fped used to select the currenly active instance
of the corresponding object but didn't change any table or loop selection to
make it active. (It did already change the frame reference.) This meant that,
upon clicking on an instance, often a different instance of the same object
would be selected. This was confusing at best.

With the below changes, table rows and loop iterations are adjusted such that 
the instance that was clicked on becomes active. If the algorithm fails, fped 
will print "__inst_select: tries exhausted" and fail safely. Please report if 
this happens.

- obj.c (search_inst, find_inst, instantiate): added mechanism to search for 
  instances matching a previous instance
- obj.c (run_loops, iterate_tables): record matches in found_* elements of the
  object's struct
- obj.c (reset_found, activate_found): helper functions to initialize and apply
  the activation leading to the instance found
- inst.c (activate_item): added comment explaining how activate_item is
  supposed to work and the fallacies of that logic
- inst.c (inst_select): added tries counter to avoid infinite recursion when
  results don't converge
- inst.c (__inst_select): when selecting an instance in the same frame, adjust
  tables and loops such that the instance becomes active
- inst.c: added call to find_inst after most instance creations (add_inst)
- obj.h: documented the meaning of the curr[ent]*, active*, and found* fields

393c178a5f Added tooltips for editable status area items. All tools are now tipped.
- gui_status.h, gui_status.c (edit_*): edit functions now accept a tooltip
- added tooltips for editable status area items
- tooltips on setup_set_type_* looked strange. Show them only for the value
  field next to the type field.

b37a8599d9 It can sometimes be unclear what exactly has been selected. To improve this,

a830226830 When no instance is selected, show the polar coordinates of the current
pointer position relative to the user origin in the radius/angle fields.
This helps to make quick manual measurements, e.g., of clearances.

This also fixes the following bug:
- gui_canvas.c (refresh_pos): showed canvas coordinates instead of model
  coordinates

9cd195bf5b When entering a name with variable expansion, the "invalid character in
variable name" error was never cleared.

- inst.c (validate_pad_name): call status_begin_reporting before expanding the
  string, to clear any previous error
- expr.c (expand): if the last character in the name is a dollar sign, print
  "incomplete variable name" instead of "invalid character [...]"

907bcf919b Fixed some bugs in the vector list re-ordering function. This should work now,
but there's another problem in the dumping code that still spoils the fun.

- inst.c (do_move_to_vec): marking algorithm propagated an uninitialized value
- inst.c (do_move_to_vec): we have to clear the marks of vectors that are 
  before the vector being moved, because they will still be visited and 
  propagated

2dffbfeaa9 When moving a vector, the list order could get confused, resulting in a
segfault, failure to update the screen content, and assigning of invalid 
references.

- gui_tools.c: removed duplicate (harmless) line 
- inst.c: when moving a vector to a new base, we may have to reorder the list
  so that the assertion vectors always follow their bases is still maintained.

c37648e2a5 Made interactive selection of measurement points a little less inefficient.
- vectors now have their own struct in inst.u and don't share inst.u.rect.end
- when selecting points for measurements, use the highlighting we've already 
  done and don't redo all the O(n^3) searching for each mouse pointer movement
- removed debug code that printed what new measurements are like. We can now 
  use the code view for that.

5a2eb77629 Made life in mil-land a little less painful.
- .fpd file format: new directive "unit" to set the default unit
- new selection was too aggressive - make it only rearrange settings if we also
  fail the second vector search
- gui_draw_pad_text: calculation of height vs. width lost too much precision,
  causing pad text to be rotated arbitrarily
- drag_new_vec: display distance in mil if unit is mil
- end_new_raw_vec: store distance in mil if unit is mil
- gridify: use a 10 mil grid if unit is mil
- ps_hline: corrected gsave/grestore mismatch
- Makefile: made "all" a prerequisite of "install"
- Postscript output now mentions the default unit (if set)
- ps_package: height and width were swapped, oopsie !

a44530f621 Selection now tries to help us not to get lost.
- postscript.c: started adding generation of object-level frames (on-going)
- gui_canvas.c: moved call to inst_deselect into inst_select, so that 
  inst_select can keep track of the previous selection (if any)
- inst_select: if clicking on the location of the previous selection, try to 
  select the next matching item
- inst_select: if we can't find an active item, try to see if we can get
  something by changing active references or - if all else fails - by 
  activating a different frame
- end_new_frame: reset the tool after placing the frame

94f4534494 - measurement offsets can now use variables. We evaluate the offset during
instantiation and create a partially formed instance. During measurement
  instantiation, we complete that instance.
- leak.supp: finally figured out how to write a valgrind suppression file
- fped.c: we don't need the FPED_NO_GUI kludge anymore
- fped.c: moved gui_cleanup_style to gui_main
- dereference icons (seems that this doesn't deallocate everything, though)

fe5f824b9e Make delete feel "safer".
- objects are now deleted by selecting them, then clicking on the delete icon
- removed tool_ops.click, which was only there because of delete

6f307d6ae7 - added KiCad output
- when saving a file, we now make a backup of any existing file with the same
  name

9c68c0de34 - File>Save now saves to a file if a second name is given on the command line,
to stdout if not
- there's no reason anymore to disallow editing the offset in new-style
  measurements
- struct inst_ops is no longer opaque, so we can avoid adding even more silly
  little access functions and open-code straightforward callbacks
- (re)stuctured hover/click/drag logic in gui_tool.c
- added optional debugging output to gui_canvas.c
- don't let a vector's base be dragged onto the vector's own end or onto one
  of its children
- measurements can now be properly changed by dragging

75d9780131 - band-aid: make canvas grab focus on click and scroll, so that it's easy to
get it back when we lose it
- improved heuristics for measx/measy: instead of looking for "next" or "max"
  on secondary coordinate, pick the one that's closest. I.e., if there's a
  chance to just connect with x' = 0 or y' = 0, do it.
- mouse wheel on loop value now selects next/previous value
- corrected proximity calculation for measurements
- vec/frame/meas toggle now deselects, so that we don't accidently leave a
  supposedly hidden item selected

4a0fd61016 More work on measurements. Getting there ...
- removed support for old-style measurements
- new-style measurements are now embedded in "struct obj", so we can dump and 
  delete them
- "measxy" is now called "meas"
- updated examples to use new-style measurements

851c82af6f - simplified tool_button and moved it from gui_tool.c to into gui_util.c
- moved make_image from gui_tool.c to into gui_util.c as well
- generalized set_frame_image and moved it to gui_util.c as set_image
- tool_button_press_event didn't check which button was pressed
- added buttons to switch visibility of frames, vectors, and measurements
- when creating a measurement through the GUI, don't invert if both points are
  minima (otherwise, one could never get the text point the other way)

751e845250 New-style measurements are coming to the GUI soon !
- moved measurement operations from gui_tools.c to new file gui_meas.c
- added support for creating new-style measurements through the GUI
- the offset is optional in new-style expressions

39690c9cb2 - to simplify communication between the various modules, renamed "ctx" to
draw_ctx, moved it to gui_util.c, and made it a global variable
- moved drawing logic for hovering and dragging into dedicated state machine
  in gui_over.c
- hovering now uses a pixmap to restore the background instead of redrawing
- moved hover drawing functions from gui_inst.c to gui_tools.c
- made hover circle thicker
