# Generate bitmaps from SVG files and other places
#
# FLATPAK builds use pregenerated bitmap files. See below;
#
# We generate different types of bitmap files depending of the platform
# Both use the common suffix .image1 (this saves lots of ugly preprocesor code)
# Unix - ascii-ized version of the .png files (using gdk_pixbuf_csource)
# Window - .xpm files (using pngtoxpm)
#
# Toolbar button icons come in 3 sizes. Separate .image1 files are generated for each size
# A small #include file (.image3) is generated for each icon, Which #include's the 3 .image1 files
# and an array definition to select the bitmap for the size
# Toolbar icons are defined as .svg file which are converated by Inkscape into .png files.
# Some of the generated bitmap are ugly and handcrafted .png files are used instead
# This live in ${CMAKE_CURRENT_SOURCE}/png
#
# Another group of icons are used as dialog decorations.
# These .png files live in ${CMAKE_CURRENT_SOURCE_DIR}
