Enhancement to #6 - right now syncing a bpy.type.Image to Unity happens under the following conditions:
Whenever a SpaceImageEditor redraws (via draw_handler_add) and the draw tool is active
Whenever the SpaceView3D redraws and the PAINT_TEXTURE tool is active
Unfortunately, 2 happens way too often - space is setup to redraw at 30-60 FPS to keep up with Unity viewport renders, the frequency for updating the texture has its own throttle but it's constantly running (thus doing a bunch of memcpys) and isn't running reactive to changes at all - unlike the SpaceImageEditor.
It's fine for smaller textures (1024x1024) but once you scale up you start to feel it chug.
