Improve SamplingOptions, and adding test cases #240
Description
Pull #236 now includes the complete SamplingOptions code from pull #181, plus a little extra/update. The last of the emulation of the previous FilterQuality is:
The last of SkFilterQuality emulation is:
FilterQuality.kHigh_SkFilterQuality -> SamplingOptions(CubicResampler.Mitchell())
FilterQuality.kMedium_SkFilterQuality ->
SamplingOptions(FilterMode.kLinear, MipmapMode.kNearest) // cpu
or SamplingOptions(FilterMode.kLinear, MipmapMode.kLinear) // gpu
FilterQuality.kLow_SkFilterQuality -> SamplingOptions(FilterMode.kLinear, SkMipmapMode.kNone)
FilterQuality.kNone_SkFilterQuality -> SamplingOptions(SkFilterMode.kNearest, SkMipmapMode.kNone)
So it turns out that the 4 filterquality settings is equivalent to 5 of the 2×3x2 =12 SamplingOptions combo (one extra, because one of them depending on whether it is rendering through CPU or GPU), and we might as well add the whole thing.
Please test the build artefact when it finishes building.
Still missing are some test code, and possibly docstring documentation too.
