// forked from keim_at_Si's Extended ColorChooser
// An extension of ColorChooser in minimalcomps with the Gimp type selectors.
// Bug fixes:
// * x and y coordinates in R, G and B screens were flipped (fixed in _updatePointer and _onCtrlChange).
// * Control pads weren't being updated after changing the color using the text field (fixed in onColorsAddedToStage).
// * ColorChooser::placeColors was using _colorsContainer.height to reposition it when _popupAlign == TOP,
// ending up with a large negative y coordinate (added override).
// * Removed unused frocessing import (thanks makc).
