Add DebugTextures to FreeTypeTools to show texture background.

This is helpful for debugging the text rendering code.

Use unrotated faces to determine text height metrics.

This fixes a bug where rotated text line spacing would change with
rotation angle.

Move templated methods to private visiblity.

Should have been there to begin with...

Style cleanup in vtkTextActor3D.

Remove pointer tests for ImageActor in vtkTextActor3D.

This ivar is always around, no need to test for it.

Strip newlines from GL2PS comments.

These are messing up the exported files.

Always upload test image if a regression test fails.

Certain failures (eg. size mismatch, missing baseline, etc) wouldn't
upload images. This patch changes vtkTesting to upload as much as
possible.

Improve aligned and rotated text.

This patch fixes aligned rotated text by anchoring the rendered image
or path to the location described by the text property's justification
properties.

As a result, alignment options are no longer ignored by the vtkTextActor3D.

Update tests and baselines.

Account for frame width in ScalarBarActor title position.

The title text was overlapping the frame using the new alignment.

Remove some unused headers and code

Just some minor cleanup

Use Round vs Floor(+.5).

Per Dave Cole's suggestion.

BlackmanHarris4 fourth coefficient was ignored.

I was plotting the frequency transfer functions of the Sinc windows
and the result for BlackmanHarris4 looked wrong.  I checked the code,
and the 4th coefficient for the window was being ignored.

Default parameter for Kaiser window is wrong.

I was previously setting the Kaiser window's alpha parameter to 3*n
where n is the window radius (the default radius is 3).  This was
wrong, the paper that I based this on was using a different Kaiser
parameter that was actually "pi*alpha".  The correct action is to
set the alpha parameter to n.

vtkOpenGLTexture: don't check for a mapped window

Checking for this means that any off screen rendering does not free its
textures because those windows are never mapped. With OSMesa, this shows
up as a memory leak because the memory is all in-process versus hardware
drivers where the memory is leaked in the driver or kernel instead.
