This makes the (currently single) storage buffer handled by GskGpuDescriptors. A side effect is that we now have support for multiple buffers in place. We just have to use it. Mixed into this commit is a complete rework of the pattern writer. Instead of writing straight into the buffer (complete with repeatedly backtracking when we have to do offscreens), write into a temporary buffer and copy into the storage buffer on committing.
