[Libreoffice] [Patch] Hover over icons produces the wrong behavior

[xapantu]

Hi,

Here are some patchs to fix this bug:
https://bugs.freedesktop.org/show_bug.cgi?id=36613

It was due to a cast between sal_Bool and sal_uInt16.

I attached different patchs, sorry, at first I wanted to separate the
tab thing and the rest of the patch, and then, I made a third patch to
fix the headers. I can merge them in a single one if you want.

There is still some issues, the button is a bit too light when it is
pressed (but there are the same problem without the patch).

Under MPL/GPL v3+. Module libs-gui (vcl).
