Description David Edmundson 2014-09-22 14:57:18 UTC 
background changes depend  goes round if width == height
ToolButtonStyle:109

button size is dependent on the background implicit sizes
(QQC ButtonStyle.qml: 155)

as far as QML is concerned: background implicit size depends on which background is chosen.
hence loop. 

Not sure on what a good fix is. Options are:
1) put the circle/square stuff in a loader put the implicit size stuff on the loader rather than the component
2) drop the if width == height check (one shouldn't meddle with sizes of buttons anyway)
3) something horrible with timers.

Drop size check for round ToolButton

It causes binding loops causing all sorts of weird behavior, like the buttons
in Klipper not always having a background.
