* QskBoxBorderColors: Use gradients instead of colors
* QskBoxBorderColors: rename API
* render gradients on borders
* boxes example: Also draw gradient borders
* calculate proper numbers of needed border colors
* fixup with example
* support rounded corners
* support more colors in rounded color gradients
I THINK WE DON'T REALLY NEED THIS COMMIT
* We don't need this commit either
* Revert "We don't need this commit either"
This reverts commit 2dc38064f7fee1d0505262fe5cebcf9e1fb16cea.
* Revert "support more colors in rounded color gradients"
This reverts commit 5754d2d0773d8273d42ae1775b53d40f5e6af26a.
* fix borders for rect ellipses
* play around a bit
* small fixes
* some helper stuff and missing stuff
* user border colors
* close to something working somehow
* works a bit better
* put it into an own function
* rearrange a bit
* something's off
* still off, but seems like we need an additional line
* works but hackish
* now it works
* bring back samples
* correction
* pimp up example
* fix normal rendering
* some more debugging etc.
* turn around gradients
* turn around rectangular gradients as well
* turn around easier
* more test cases
* fix fill case
* more test cases
* clean up a bit
* clean up example
* clean up some more
* incorporate feedback from Uwe
* fix bug when using horizontal gradients
* add QskArcNode and QskArcRenderer
* IOT example: Use QskArcNode instead of own arc node
* move some functionality to the arc renderer
* add QskArcMetrics
* add methods to QskSkinlet
* remove circular bar graph node
We can now use updateArcNode() and don't need our own method.
* support linear gradients in the arc renderer
* clean up
* incorporate Uwe's changes
* add overloads for updateArcNode() when the angles are set dynamically
The angles don't always come from the style, so we need overloads
in QskSkinlet to set them dynamically.
