Hi,
I'd found such strange behavior of the dfb_surface_pools_negotiate()
function. In branch 1.0.0 my code was working fine.
My source:
DFBSurfaceDescription desc;
memset(&desc,0,sizeof(DFBSurfaceDescription));
desc.flags =
(DSDESC_CAPS|DSDESC_WIDTH|DSDESC_HEIGHT|DSDESC_PIXELFORMAT|DSDESC_PREALLOCATED;
desc.caps = DSCAPS_SYSTEMONLY;
desc.pixelformat = pix_format;
desc.height = height;
desc.width = width;
desc.preallocated[0].data = src;
desc.preallocated[0].pitch = bytes_per_line;
The surface is created without any problems.
Then I invoke the Blit() and it fails when
dfb_surface_pools_negotiate() returns the error UNSUPPORTED for source
surface.
Call stack:

ret_pools=0x7fd8b7c0, max_pools=4, ret_num=0x7fd8b7f4)

I have not enough experience to dig deeper. I'm afraid it will take
too much time.:(
