Axel Dörfler a00fcbcdf8 Improved BSlider class:
- rewrote GetPreferredSize(), it now actually works correctly
- BSlider is certainly not supposed to resize itself on creation
- fixed BarFrame() and ThumbFrame() to support a different view frame
  than the ideal one
- added SetBarThickness() support
- refactored constraining the mouse point to _ConstrainPoint() - it's
  now used by MouseDown() and MouseMoved() - because of that, tracking
  now works with vertical sliders as well
- still has some drawing problems, but less
- _ReservedSlider4() was defined public for the R5 build
Cleanup, more or less rewrote the header.
