No. But, it would fit into the new imaging code quite easily.
Specifically, you'd patch it into _mesa_unpack_ubyte_color_span()
in image.c where there's a comment about convolution and histogram.
Also, the matrix-related functions would need to be extended for
the new color matrix.
Note that color matrices are part of the OpenGL 1.2 ARB_imaging
subset. That's a lot of stuff to implement. However, there's
the GL_SGI_color_matrix extension which just implements the
color matrix. That would be a more reasonable project. See
