Last change on this file since 2791fbb7 was 7470d97, checked in by Jiri Svoboda <jiri@…>, 4 years ago

Add GC operation to set clipping rectangle

The number of changed files is due to the proliferation of GC
implementations, mostly these are just dummies in unit tests.
Definitely need to tame those in the future.
