This is a QT module that provides color management, e.g. a color wheel. https://gitlab.com/mattia.basaglia/Qt-Color-Widgets

I'm adding this as a dependency for drawpile which I will also submit once this package definition is merged. There is unfortunately no release available for this, however drawpile bundles it's own copy of qtcolorwidgets if it doesn't find one.

Thank you.  I pushed a modified version to the master branch with commit
b16640ac0.

Changes:

- added comments about the lack of a public release
- changed the version string, because “git” is not a valid version string
- wrapped the package definition in a let binding providing the commit and the
  Guix revision
- changed the comment style (margin comments use only one semicolon)
- expanded the description.
