In fact, pixman exposes only double matrices at this point, so the server implementation stores both fixed point and floating point variants in that format. However, a GPU will likely want to stick with 32 bit values, which is why I expressed the protocol using 32 bit floats; 64-bit computation in the GPU is generally much slower than 32-bit. -- [email protected]
