Bug Description
If I middle click to create a color with 0 opacity then trying to use that color with the pencil tool has no effect.
This works fine though if you use the paint bucket, but I need it to work with the pencil tool for changing single pixels without also changing other connected pixels of the same color.
As I recall this didn't work right out of the box with paint.net either, but you can get this working on paint.net by changing something like 'composition mode' from something like 'blend' to 'overwrite'.

I've started to look at the source for this, and it appears that perhaps the bug is actually that the paint bucket tool is not honoring the blend settings under the hood.
PaintBucketTool does not use UserBlendOps. NormalBlendOp. ApplyStatic to combine with the existing color, so just overwrites what is there using ColorBgra. ToPremultiplied Alpha.
I guess what really needs to happen is the addition of a new 'OverwriteBlendOp' and the exposure of the blendop being used in the gui, in a similar way to Paint.net
