Jonas Jenwald 32a0b6fa73 Move some constants and helper functions out of the PartialEvaluator closure
This will simplify the `class` conversion in the next patch, and with modern JavaScript the moved code is still limited to the current module scope.

*Please note:* For improved consistency with our usual formatting, the `TILING_PATTERN`/`SHADING_PATTERN` constants where re-factored slightly.
