d3d9: Use more reasonable texture dimensions. 

caps.MaxTextureWidth / caps.MaxTextureHeight can potentially be very
large, which could cause a driver to run out of memory. Arguably the
driver shouldn't report such large limits, but there's no reason for
us to create a texture larger than 1024x1024 either.
