Multi-gene visualization in a single DimPlot with blended color

[mitsiask]

Greetings,
really nice work, thank you very much for sharing it with the community.

I would like to ask the developers about a particular functionality of DimPlots, that could be very useful to add to your features.

In particular, the combined visualization of two genes in a single DimPlot, with blended color in cells with overlapping expression from both genes, would be very useful. An example of such a visualization is illustrated in Seurat's visualization vignette: https://satijalab.org/seurat/articles/visualization_vignette.html , and in particular in the [FeaturePlot](https://satijalab.org/seurat/reference/FeaturePlot.html)(pbm[c](https://rdrr.io/r/base/c.html)3k.final, features = c("MS4A1", "CD79A"), blend = TRUE) code example.

Cheers

Hey there! Thanks so much for the kind note and the suggestion!

This is an interesting idea. I'd not noticed this Seurat feature add before, but it definitely seems like it shouldn't be too hard to mimic. Putting it into my list of likely adds for the next Bioconductor release cycle, along with the dittoPlot with multiple genes idea in #99.
