To generate (TGA) image files using u8g2 on a regular (non-Arduino)
system, have a look at the sys/bitmap directory, which is the
recommended way to approach this. This sys/tga directory is mostly kept
around for compatibility and to generate u8g2 manual images.

# gm.map
#
# Syntax:
# 'hash' introduces a comment
# tile <ascii> <mapto> <top> <right> <bottom> <left>
# map the <ascii> code to the specified <mapto> code, if the other for tiles match
# If one of the other four tiles is 0, then ignore this tile (wildcard)
# thing ... same as tile, but can be redefined at any time, should redefine to char
# itemkey <iname> <ascii> <bg-tile> ... similar thing, but will connect to an item and assign the <backgroundmapto> instead
#
# summery:
# tile: static fixed thing for all maps
# thing: static thing for some maps
# itemkey: dynamic objects like changing doors, boxes or monsters
#
# item <iname> <foregroundmapto>
# defines a global template for an object.
# anyting on the map, which might disappear, move or change has to be an item
# itemuse <iname> <ascii>
# only within active map. <mapto> will be the background tile for the char
# the current foreground tile might still be differrent and is set during iteminit
# connects the ascii char with the given ascii char on the map to get the xy pos.
# iteminit <iname>
# <procedure>
# endproc
# procedure, which is called, when the item is created,
# receives position, where it should be created on the map
# itemhit <iname>
# procedure, which is called, when the item is hit by something
# - returns 0 if the item hitting item has to be stopped
# - may move itself
# - may change its own shape (tile)
# - may modify its status
# endproc
#
# example "normal door, status=closed"
# 1. hit: status=open, change tile to open door, return 0
# 2. hit: return 1 (hero can pass)
# example "creature, status=5 life"
# 1. hit: get hitting obj attac damage, reduce life --> status=2, apply attack damage hitting object, return 0
# 2. hit: get hitting obj attac damage, reduce life --> status=0, remove object from map, return 0
# 3. hero can continue
#
# itemstep <iname>
# executed every step
# - moving items can move towards hero or others
# endproc
# mapinit
# executed during map init
# endproc
#
#
# map <name> <width> <height>
# Create a map with the given name and size. this must be followed by :
# endmap
# Finish the current map
