Selected text has incorrect background colour when an SDF font is used

[nixbody]

There seems to be some problem with SignedDistanceField shader which causes selected text to have the same background colour as is set as text colour. That makes the selected text ureadable because it just blends with the background. Setting TextInput.selectionTile manually has no effect with SDF fonts.

This only seems to happen when I call hxd.res.BitmapFont.toSdfFont() with h2d.Font.SDFChannel.Alpha (which is needed for SDF fonts generated by Hiero).

Thanks for pointing this out, thought I was using it wrong. As a workaround I just use a non-sdf font for the text input which I don't think should be a huge deal since text inputs don't generally have large blocks of text so super-crisp fonts aren't that important.

To generate SDF fonts instead of Hiero you can use Fontgen which uses RGB instead of alpha channel, and then selection colour is calculated correctly. It's Windows-only but it works in Wine.
