Summarize your change.
This implements onion skin management. From the original PR text:
Added 5 properties into the PaintIPNode node:
onionShow : enabled/disabled the drawing of onionSkin (default is false).
onionBeforeFrame: the number of frames BEFORE a stroke on which the onionSkins will be drawn (default is 5).
onionAfterFrame: the number of frames AFTER a stroke on which the onionSkins will be drawn (default is 5).
onionBeforeColor: the color used to draw onionSkin BEFORE (default is red).
onionAfterColor: the color used to draw onionSkin AFTER (default is green).
Paint::PolyLine and Paint::Text now manage those new properties and draw onionSkin on previous / next frames with the appropriate fading out colors.
Modified the annotate rv-package:
Modified drawpane.ui to add the appropriate Ui to manage the above new properties.
Modified annotate_mode.mu to properly handle the colorChooser with those new Ui.
Describe the reason for the change.
There is no change from the original PR - except for resolving merge conflicts and bringing up to date with the latest OpenRV main.
