Matteo Bruni (@Mystral) commented about dlls/d3dx9_36/surface.c:
UINT x, y, z; TRACE("src %p, src_row_pitch %u, src_slice_pitch %u, src_size %p, src_format %p, dst %p, "
"dst_row_pitch %u, dst_slice_pitch %u, dst_size %p, dst_format %p, color_key 0x%08lx, palette %p.\n",
"dst_row_pitch %u, dst_slice_pitch %u, dst_size %p, dst_format %p, color_key %p, palette %p.\n",
It might be nice to introduce a small `debugstr_color_key()` helper to show the full color key interval as it was computed.
