----- Original Message -----Don't check if there's sampler support for stencil if we're not going to actually blit/copy stencil values. Fixes the case where we mistakenly said we can't support a blit of depth values from S8Z24 to X8Z24. Also, rename the is_stencil variable to dst_has_stencil to improve readability.

Thanks. I'm hoping that Marek can also review since he's the original author...
