[MACTCL] Tk-Cocoa 2.0 (tcl/tk 8.6.4) and autoscroll on a text widget.

[Andrew S. <and...@qu...>]

Following the discussions here of Tk-Cocoa 2.0, I have downloaded and built
tcl/tk 8.6.4 and to try out. Unfortunately, there seems to be a regression
when autoscrolling a text widget -- the scrollbar's "bar" is not visible.

I have boiled the issue down to a simple script, which follows, and have
attached screenshots from 8.6.3 and 8.6.4.

Thank you Kevin for all the work on Tk-Cocoa,

Andrew Stein
