Elias Naur 88fb798cca gpu: [compute] speed up path comparisons with op keys ...

To re-use previously cached layers, the compute renderer must know
whether two drawing operations are equal. In the case two operations are
not equal, a fast hash comparison will most likely fail. In the case two
equal operations with complicated clipping paths, the comparison of the
path data is expensive.

This change adds support for fast ops.Key comparisons, where two paths
are equal if their ops.Key are. This is an optimization that kicks in
for text rendering, where glyph clipping shapes are re-used across
frames.
