Workaround this by passing dst as both src and dst to the second one. The drawback is that the second convolution would not run in multiple threads but at least it yields correct result.

This fixes segfault in GP_PixelRGBMatch() and GP_PixelRGBLookup() when currently matched pixel in table is not RGB (by skipping all pixels that aren't). NOTE: This was found on paletted framebuffer where (for obvious reasons) correct pixel wasn't found and the framebuffer backend initialization segfaulted while trying to match pixel type (on GP_PIXEL_G8 on NULL dereference).
