manuelk c646ac2e3c Refactor & cleanup patch interpolation
- move patch interpolation code out of Far::PatchTables into far/interpolate
- add bilinear quad interpolation function with derivatives
- switch OsdCpuEvalLimitController to far/interpolate
- add support for bilinear quad interpolation & clean varying interpolation
