Refix invalid glTexImage2D operation in FramebufferObject
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." https://registry.khronos.org/OpenGL-Refpages/gl4/html/glTexImage2D.xhtml This modifies ba9e57d65f15c935632b0ad22db0bead9a7d5f90.
