I see it in there, but i get a ToDo: error. Is it entirely unsupported, or is there a workaround that doesn't involve making a nearest-power-of-two texture?
Support for GL_ARB_texture_rectangle is now in the OpenGL package repository at http://darcs.haskell.org/packages/OpenGL/. I haven't released a new version on Hackage yet, because the support for generic vertex attributes (something totally unrelated to rectangular textures) hasn't been finished yet. To explain this a bit more: I'm a bit reluctant to release an API which might immediately change in the next release. The tricky part here is that OpenGL 3.1 differentiates between 3 ways of handling integral vertex attributes: Conversion to normalized floating point, conversion to unnormalized floating point, and keeping integral values. This is not yet really reflected in the current API in the repository. Cheers, S.
