Will it be able to load and save PNG?
Things you can do with the current version:
a) draw an invisible rectangle (linewidth 0) and fill it with any bitmap loadable through datatypes.
(current versions will leave some artefacts if source bitmap has semi-transparent areas)
b) repeat as often as needed
d) Export as PNG with any resolution you need
With next version:
c) set background color to 100% transparent
Directly loading PNG is not supported as it's still a vector based app.
@Heiroglyph
If you want us to suggest you a coding project you should start with giving some pointers as to what skills you have and what kind of project you'd like.
Some small 10k utility or 100MB of sources ?
Game or app ?
Ported or all your own ?
Heavy on GUI or just interested in algorythms ?
etc etc
