problems with Aqua Tcl/Tk core_8_5_branch 2015-04-28

I built Tcl/Tk core_8_5_branch from the 2015-04-28 commit (in the git 
mirror) on OS X 10.9 with MACOS_X_DEPLOYMENT_TARGET=10.6. Visually the 
results are not as nice as code using the 2015-03-24 commit. It seems 
that many widgets, including labels and texts, take up far more room 
than they used to, with the extra room used for unnecessary whitespace. 
The results is far more different from Unix than it used to be.

One improvement is that button text is now displayed with some padding, 
making them much more readable, and more like unix (in a good way, since 
it is easier to write cross-platform code; I had been adding padding on 
OS X). But it seems that too many other controls got the same treatment, 
even if they didn't need it.

Also, both versions of Tcl/Tk have a bug whereby windows are often 
impossible to close. Clicking the close control and typing cmd-W both do 
nothing. Fortunately they can still be minimized, but it's disturbing 
not to be able to close them. Unfortunately this is intermittent, though 
common, making it hard to present a small example. Has anyone else seen 
this?
