Daniel van Vugt 38da479ee8 slider: Calculate handle position in whole pixel units
`-slider-handle-radius` is a floating point value and even in the default
theme it's not a whole number. Regardless of the fractional part that's
still going to occupy a whole extra pixel with antialiasing. So make room
for it. Otherwise it looks clipped, which it is by the Cairo context of
its `StDrawingArea`.
