anything opengl is an example of this. it's nearly impossible to do
opengl for plan9 using libdraw primitives, since converting a ulong to
a color needs to go through allocimage.
i heard someone suggest using an rgb color triangle already
allocimage'd in rio as a source for pre-allocated colors, but try
drawing a replicated pixel sourced from a larger image without a 1x1
intermediary :)
