Fix regression when using Windows XP with QVTKWidget.

When another app window is passing over a QVTKWidget, there was some
uncessary flicker on Windows XP.  The flicker was caused by an
extra InvalidateRect() call that we actually need for Vista and newer.

BUG: AMR Readers crash TestEmptyInput test

The AMR readers are crashing the TestEmptyInput test. This patch
exempts those readers from the test since they do not have a
SetInputData method. Other readers have been exempted in the past.

COMP: Use temp dir for TestOggTheoraWriter

The test is failing on a few platforms. It trys to write in the
current directory. Tests should write files into the temp directory.
Perhaps this wil fix those tests.

COMP: Regression test failures on some platforms

Some windows and linux systems fail the regression tests by minor
amounts. This patch specifies a larger image tolerance.

In particular, the VTK continuous build has a recurring regression
failure for one of these tests. With the increased tolerance, the test
passes.

Tolerances were set so that the tests pass on a Fedora/Mesa system and
were verified on a Fedora/OpenGL system.

Fix MeshQuality Python test.

A new python version called MeshQuality.py has been
 written, it is based on MeshQuality.cxx.

The old meshQuality.py has been deleted.

The new version tests mesh quality more thoroughly than
 the old version and produces the same output
 as MeshQuality.cxx.
