Common -D flags that can be used with Heaps:
# flag to define the size of the window and default scene size:
-D windowSize=800x600
# define the window/process name
-D windowTitle=My game made with Heaps.io
# define the path to the game assets/resources
# (actually not recommended, just use `-p res` insead,
# but which demands assets to be in a directory called `res`)
-D resourcesPath=assets
# so rather use:
-p res
# other known flags (deprecated/legacy code)
-D heaps_emit_tile_buffering
