also set(x, y, image) y reversed in openGL (normally would be a separate bug but it's tied
to this issue as it turns out)

while not particularly difficult to fix, the priority of this issue is low because if you're doing a
bunch of pixel access stuff, you're not gonna get the speed improvements of opengl, so in
fact it may not even be faster than P3D, and in some cases, very likely could be slower.

hm, safari seems to have something about forcing word wrap.

the bug here is that pixel operations are almost entirely broken for opengl.. not sure if i've
included all the functions, but that's the gist of it.

casey has added an example of the problem with copy() to bug #274.

background(image) also falls under this category

now fixed for release 0127.

I seem to still be experiencing this problem, at least with
PApplet.background(PImage) as of v135 on WinXP with the GL renderee, though
calling image(pimg, 0, 0) seems fine as a workaround... -dch
