PR3318: Fix compatibility with vanilla Fontconfig
Contributed-by: Matthias Dahl <ml_openjdk-lists at binary-island.eu>
With vanilla Fontconfig, most text is not rendered.
The "Infinality"-patched Fontconfig with its own configuration,
supplies an additional config file that sets the antialias key
(FC_ANTIALIAS) which is not part of the vanilla Fontconfig and also
has no default in its source code.
In the case that FC_ANTIALIAS is not being provided for a given font
because the font does not contain the appropriate information (which
is quite common) or a specific config file is missing,
FcPatternGetBool for the key will return an error and no valid
result. Thus, ftRenderMode stays uninitialized due to the way its
initialized in the conditional constructs, eventually causing the text
rendering anomaly.
Furthermore, the logic is flawed as well. The specific subpixel
rendering modes are only properly set if FC_ANTIALIAS is set and true,
no matter what was requested by the caller (aaType).
This patch makes the following changes to address those problems:
1. ftRenderMode is always properly initialized.
2. FC_ANTIALIAS is only evaluated if antialiasing was requested and only
used to turn off antialiasing if that is suggested by Fontconfig.
3. Subpixel rendering modes are properly set according to Fontconfig
results and only if subpixel rendering was actually requested.
In order to properly adjust for the "forced off" antialiasing, it is
necessary to change the signature of readFontconfig and give it full
access to FTScalerContext, so it can properly set the new aaType.

PR3318: Fix glyph y advance
Contributed-by: Matthias Dahl <ml_openjdk-lists at binary-island.eu>
The y advance needs to be negated as the final step, otherwise the
rounding will naturally be wrong.
This did show itself for example as shifted into each other glyphs in
Android Studio for text where a rotation was applied (e.g. scale on
the ui builder).

PR3318: Always round glyph advance in 26.6 space
Contributed-by: Matthias Dahl <ml_openjdk-lists at binary-island.eu>
By rounding in the 26.6 space, the glyph advance can be snapped to the
next 64 boundary by integer arithmetic alone, thus avoiding floating
arithmetic and improving accuracy.

PR3318: Simplify glyph advance handling
Contributed-by: Matthias Dahl <ml_openjdk-lists at binary-island.eu>
Reduce the branches and always round and convert the advance, no matter
if its zero or not since it is guaranteed that 0 divided by a floating
point always equals zero.
