Casting away the const isn't very nice. It also seems unnecessary.

This patch made me look back to this hunk from D3DX10GetImageInfoFromMemory():

if (img_info->ImageFileFormat == D3DX10_IFF_DDS)
{
    ...
}
else
{
    ...
    img_info->Format = DXGI_FORMAT_R8G8B8A8_UNORM;
    ...
}

That seems suspicious, can't formats other than DDS (e.g. WMP) support
higher bit depths with d3dx10?
