How about providing access to a graphics library for Lua, like Lua-GD?

Lua-GD

(The build process for Macs apparently isn't very easy.)

You will see more of the imaging features in the coming drops

Awesome, looking forward to it.

hoping the ability to manipulate an images colour is coming up!

I'm hoping for filled polygons.

Looking forward to drawing images and primitives onto other images. Please :-)

Desperately needing this!

Yes, I need a feature like that, a buffered Image which I can paint Image, Rect, Circle into it.

Currently on Corona SDK, The frame rate is slower and slower when I add more object to displayGroup.

I can't use Corona right now because of exactly this. Maintaining thousands of display objects is very inefficient, compare to painting a buffered image and appending more shapes to it incrementally.
