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.

ce1e7cdb 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.

85499309 BUG #13706: enable VTK_CURSOR_CROSSHAIR for vtkXOpenGLRenderWindow

With cursor themes, XC_crosshair is a perfectly nice cursor under X,
so it makes no sense to fall back to an arrow cursor instead.

Work for this fix has been sponsored by BP.

9e8594e1 BUG: Correct CMake message typos: FATAL -> FATAL_ERROR

FATAL will just be emitted as message text, FATAL_ERROR
actually triggers the intended "stop configuring now"
behavior.

Also, messge -> message.

Most of these occurrences are luckily (?) in conditionals
where they are rarely encountered in practice.

These two tests need a bit more time to run on the ubuntu factory
machine. Here we increase the time to 120 seconds, just for these two
tests. The rationale is to have clean factory builds for gerrit
reviews.

Change-Id: I7ad2e9abd7a657ed2c9918d53006cd991098cdbc

TestRenderView fails on some platforms, reporting:
X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  73 (X_GetImage)

This patch changes the test to use the newer testing framework and
seems to fix the problem.
