- 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 git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5405 99fdad57-331a-0410-800a-d7fa5415bdb3
