- disable framebuffers for camera textures in legacy mode entirely. This depends on a GL_DEPTH24_STENCIL8 surface which most of these old chipsets do not support, and I really see no point to invest any work here. The worst that can happen is that oversized camera textures won't be processed, which, due to general performance issues, might even be a good thing.
