pngcairo performance on Windows

[Allin C. <cot...@wf...>]

It seems there is something not quite right with font-handling
under the pngcairo terminal on Windows.  I suspect the problem
lies somewhere in the pango/cairo stack for Windows but I thought
I'd start here in case anyone has any ideas.

The issue is that the extremities of text get clipped in some
contexts. This is with CVS gnuplot built for win32 with
pango/cairo support.  I haven't seen this using pngcairo on Linux.

I suppose the first thing is to see if others can replicate the
problem.  I've put a simple test file and four examples of PNG
output (v8.png uses the verdana font at 8 points and v9 uses
verdana at 9 points; the others use the default font for
pngcairo).  These PNGs show bits of the letter 'Q' being clipped,
plus, in some cases, bits of the x-axis numerals missing.

Do others see this?
