<pre>The piglit
ext_framebuffer_multisample-fast-clear GL_ARB_texture_float
fails with an assertion raised if the GL_INTENSITY16F texture format is
emulated by PIPE_FORMAT_L16A16_FLOAT that is actually picked by Gallium if no
relevant intensity format is available.
The problem is that in this case
glGetTexLevelParameteriv(..., GL_TEXTURE_INTENSITY_SIZE, ...)
will return a zero component size because the texture info us read from the
used replacement format that specifies that the intensity component size is 0,
and as a fallback only RG is expected.</pre>
