Elias Naur 5197f637a7 gpu: [compute] compute and store clipping path hashes during construction ...

The hash of the clipping paths that affect drawing operations are computed
and used to quickly determine that two operations are not equal, the
most likely outcome of a comparison.

However, for paths that are constructed once and cached computing the
hash at every frame is wasteful. This is especially true for text, which
is both cached and also among the largest paths in a frame.

This change moves the hashing to op/clip.Path construction time, and
stores the hash in the ops list so it won't be re-computed at every use.
