st: Quartz2D graph rendering may be problematic in MacOSX

[Tom Trikalinos <ttrikalin@mac.com>]

Hi to all:

Seems that Stata's Quartz2D graphics rendering is problematic (MacOSX 
flavor).

In some graphs the axis labels may be displaced.
This may be fixed with resizing of the graph window, or may get worse.
Reciprocally, resizing may displace otherwise perfectly drawn labels.

The following meaningless example reproduces the problem
. preserve
. sysuse auto, clear
. scatter mpg weight, ylabel(10 "1000" 20 30 "3000" 40, angle(0))  // 
resizing fixes or distorts labels
. restore

A crude workaround is to use Quickdraw rendering. Exporting as eps, pdf 
or whatever yields a perfect graph.
I recall that this was an issue a few months ago; may have surfaced 
again after the most recent MacOSX update.

I'm running Intercooled Stata 8.2 (born 10 Jan 2005) on a fully updated 
Mac (Panther 10.3.8)
