vtkTextMapper improperly renders empty strings. Instead of rendering nothing, as
expected for an empty string, a rectangle is rendered. The rectangle is visible
only when the text property's background is not completely transparent.

This commit fixes the problem at two levels: in vtkFreeTypeTools and in
vtkTextMapper.

vtkFreeTypeTools now checks for an empty string when rendering to an image.
Without this check, rendering an empty string results in the small rectangle.

vtkTextMapper::RenderOverlay() is updated to handle the case of an empty image.
This also serves as a revised solution to #15787:

Avoid passing unused array values to the vtkFunctionParser for each tuple.
This was causing the vtkArrayCalculator to get slower as the number
of available arrays in the dataset increased even when the function
remain unchanged.

This was already documented in README.md

Certain places were using ints instead of vtkIdType resulting in segmentation
faults for large datasets. This fix is based on vtkSynchronizedTemplates3D

Without this, static MSVC builds don't compile ('FILE' isn't defined).

Some of these are common identifiers (col, pos, etc.) and are
causing identifier collisions/shadow var warnings on MSVC.

Updated the variable names to use VTK style while refactoring.

Since vtkArrayListTemplate.h includes vtkArrayListTemplate.txx, all
non-templated methods defined in the implementation file need to
be marked inline to prevent warnings about ODR violations on static
msvc builds.

The included file was pulling in <cassert> and defining the Win32
assert implementation '_wassert' both inside and outside of the
anonymous namespace, leading to ambiguous function call errors on
static debug win32 builds.
