Another consideration in addition to accuracy is latency.

I suppose a compositor may want to disable features such as PSR for use-cases 
requiring low latency. Touch and stylus input are some examples.

I wonder if flags would work better than enums? A compositor can set something 
like `REQUIRE_ACCURACY & REQUIRE_LOW_LATENCY`, for example.
