Created on top of #38, this pull request provides
set_channel(),add_to_channel(),multiply_channel(),raise_channel(), andcap_channel()versions (suffixed with_native) that operate on native encoding colours (those from nativeRaster objects).As the other pull requests this is based on, this is part of tidyverse/ggplot2#4989, which aims to improve the performance of ggplot when rasterizing a large matrix.
My plan when this gets merged is to propose enhancements in the scales package that leverage these patches and that can be used by ggplot2 to perform better.
I don't have further patches planned for farver.
