Old setColor methods renamed to setColors. Note setColors may soon be changed to something better.

Changes
Fixed label pref size when using font scale.

Widgets now use setSize instead of setWidth/Height.

This avoids computing the pref size twice, since setWidth calls sizeChanged which invalidates.
Should not have been committed.
