Spritesheets are probably more used in games,
and MX2 is (and should be) not limited to games only.
In Windows you would call it ImageList for using
with Toolbars, etc.
IncBin that creates an C++ array or memory-pointer would be nice,
for loading assets/data (images/sounds/music/sprites/txt/ico/cur/…) directly
from memory, using a memory address (void ptr).
Especially to create stand-alone executables on the desktop-targets.
