The affected libraries are fontconfig, freetype, harfbuzz, libpng, libjpeg,
sqlite, pcre, and zlib.
* On Darwin, by default, fontconfig is disabled and all of the other
libraries are bundled.
* On non-Darwin, by default, fontconfig is enabled and system-provided
freetype, libpng, libjpeg, and zlib are used. Harfbuzz, pcre, and sqlite
continue to be bundled.
* Individual libraries from the above list may now be enabled or disabled
on the build.sh command line with e.g. --freetype=system or
--freetype=bundled.
* The existing --system-qtdeps, --system-qt, --system-qtwebkit options
have been renamed --qtdeps=system, --qt=system, --qtwebkit=system
respectively. New option --qtdeps=bundled forces all available
bundled libraries to be used.
Also:
* Slight adjustments to organization of preconfig.sh.
* Can now disable PulseAudio and ALSA.
* Directly link OpenSSL instead of loading it at runtime.
* Clarify the pkg-config situation (it must be enabled if and only if
sqlite comes from the system).
By implementing a dummy platform native interface (for now, it may be
extended in the near future), QPlatformPrinterSupportPlugin will avoid
the path of loading the printer support plugin
(QCocoaPrinterSupportPlugin on OS X).

It cannot, nor should it, be selected on windows machines. There, we
stick to the Windows QPA which is required to get a lot of things up
and running, like an eventloop, socket integration etc. pp.
There was code in the phantom QPA to make it compile, but it never
actually worked since a lot of things where missing (such as
instantiating QWindowsContext among others).

The PhantomJS QPA hardcoded usage of QFontconfigDatabase on
Unix-not-OSX, causing build failures in "bundle all the libraries" mode.
Use QGenericUnixFontDatabase instead, which is QFontconfigDatabase if
fontconfig is enabled, and QBasicFontDatabase if it isn't. This means
that the bundled-qtdeps build will use only the fonts bundled with Qt,
and won't be able to find them on a machine that doesn't have the source
tree, which is suboptimal, but at least this makes the bundled-qtdeps
build complete successfully again.
Part of issue #12467.
In this mode, system-provided libraries will be used for all of
Qt's dependencies, but Qt and QtWebkit themselves are still the
bundled copies. This mode actually works.
Now that this mode exists, disable fontconfig in the "everything
bundled" mode, because it drags in the system freetype and several
other system libraries. (There is no bundled fontconfig.)
Part of issue #12467.
* build.sh now handles building qt and qtwebkit.
* preconfig.sh is now only responsible for accumulating arguments
to pass to qt's configure script.
* preconfig.sh doesn't have command line arguments of its own;
anything on its command line will be passed directly to qt's
configure script.
* first pass of adjustments to the qt configure parameters
to try to get a more static build - unfortunately, system
sqlite, libz, libpng, and libexpat are still getting pulled
in somehow (mostly via fontconfig, I think).
Part of issue #12467.
PDFs are not rendered like PNG or other image formats by phantomjs because it
uses the printer functionality of Qt+Webkit. But Webkit uses some printer
"optimization" to save paper by shrinking the output. Such shrinking results in
too small content on a page.

accurate for .pdf")
Exotic text (e.g. attempting to render a binary file such as .zip
or .exe as a webpage) can trigger an assertion failure in the
Harfbuzz code. Chromium developers also noticed this issue and
committed a patch to fix it:
http://lists.freedesktop.org/archives/harfbuzz/2009-August/000354.html
This patch has not been accepted by upstream, but this (old) version
of Harfbuzz has been abandoned and superceded by Harfbuzz-NG.

This is just a workaround. We simply avoid removing the custom font
(intentionally leak it, a small price to pay) because otherwise it will
invalidate Qt's font cache, which in turns trigger the crash at
CoreText's CTFontCopyGraphicsFont.

For our QPA/Lighthouse platform screen, apparently we need to specify the
physical screen size because otherwise the default 100 dpi will be used.
This also brings font rendering on headless Linux to 72 dpi.

Modern browser mostly limit re-directs to 20. The current limit in PhantomJS is 10 which is not in line with most browsers. This patch is a simple increase of gMaxRedirections from 10 to 20.
