[Tile-dev] modified themes for labelframes

[Jeff H. <je...@Ac...>]

I'm porting more stuff to OS X, and finding that the alternate
grouping controls (essentially labelframes) might be nice to
have.  See:

ines/XHIGLayout/chapter_19_section_4.html

We should be able to reproduce these in styles, but the current
labelframe drawing disallows that.  It has a -borderwidth, but
that is ignored for anything but adjusting the label inset (at
size 0, it still draws the border, Windows and OS X).

On OS X it seems that for drawing themed groupboxes, there is
only the one API func.  So I'm wondering ... is this an
instance of something tile styles should support, or is this
something where a snidget is more appropriate?

Essentially, I want the option:

	labelframe .foo -style whitespace|bordered|separator

with other options (like -inset) for control of whitespace.
Currently tile only does bordered, while the classic labelframe
could improvise the whitespace variant (by asking for -relief
flat -bd 4 or something).  The separator would be tricky, but
possible (use classic labelframe with a widget, no border).

However, I'd like to this tile styles could handle this ...
ideas?
