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. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@13342 a95241bf-73f2-0310-859d-f6bbb57e9c96
