A recent change fixed the texture format parameter to be RGB instead
of RGBA for opaque internal formats. However, this broke the RGB10
case, since the pixel type is then GL_UNSIGNED_INT_2_10_10_10_REV. The
doc says:
"GL_INVALID_OPERATION is generated if type is [...]
GL_UNSIGNED_INT_2_10_10_10_REV [...] and format is neither GL_RGBA nor
GL_BGRA."
