It'd be nice if loadPixels() set a boolean and updatePixels() unset it, so that you could determine whether or not you need to loadPixels() again in order to avoid overwriting previous changes.

yup, that's on the todo. updatePixels is just a flag since it can't force an update, but can only request it the next time that the image is rendererd (since the renderers are completely detached from the image data).

so basically loadPixels() needs to not do its thing unless updatePixels() has been run properly.

load/updatePixels kinda stinks but it's what we have to do for java2d and opengl. it's probably gonna be a little bumpy since we haven't really worked out the kinks with it yet Undecided

(edit) there's also a weird situation that can happen where you call updatePixels() and then start drawing with line() or whatever, and things may not update properly.. gotta straighten that out.
