The -tile method now leaves the frame height unchanged instead of
sizingToFit the theme attribute « min-size ».
The « min-size » is still in use when we layout the ephemeral subviews.
This is how other controls with a min-size work.
Also added -minimumFrameSize. This CPControl subclass will return the
frame for sizeToFit, i.e. when you want to sync the frame attribute
with the minimum/visible height.
Tests : CPSegmentedControlTest & Nib2CibAlignment manual tests.
Fixes: #2341
Added manual test showing fix for setLabel:forSegment for flexible
segments.
Added ojtest showing that the selection is preserved when a selected
segment is removed.
- Get the scroller orientation from the xib.
- Fix the nonsensical calculation of _isVertical when given bounds.
- Since orientation comes from the xib, had to re-nib2cib everything to be safe.
