My bad. fbo_color_attachments is not what I recalled from when I first
looked at the Tegra information. Thanks for correcting me.

NVIDIA bad too. OES_texture_half_float does not change the OpenGL ES 2.0
specification language that says no (internal) formats other than a
small list of integer formats are color-renderable. They should have
made an extension.
