widget: Add hack to make label mnemonics work again

Browse Source 
Mnemonics for characters that go beyond the baseline (q, y, g) were not
being shown, because they are drawn outside of the label's allocated
size.
This patch just disables the clip-to-size for labels, so that the label
can draw outsize of its allocation. In most cases, that works around
this bug.
