Playscii 0.9.11

Art Mode:

• Give a useful error instead of crashing if user tries to export an image larger than their hardware's max supported texture size. Log the max supported texture size on startup.
• Fixed art layers with a Z greater than 1 not showing up in PNG image exports
• Ignore "inactive layer visibility" setting when exporting images
• Fixed crash in "img" console command if image file not found

Game Mode:

• Added GameObject.consume_mouse_events, objects with this set true will prevent any more mouse event handling from other objects being clicked/wheel'd
• Fixed bug in GameObject.get_edges for objects with non-default art_off_pct_x/y values
• Locked game objects properly handle mouse clicks and wheel movement when edit UI is off (aka "play mode")

platform work:

• Fix shader errors on macOS introduced by some Raspberry Pi work from beginning of this year
