Instead of requiring that QPlatformFontDatabase::populateFontDatabase()
populates every single font in the system by calling registerFont(), we
now allow the platform database to call registerFontFamily() instead, and
then keep track of which families we've yet to fully populate in the font
database.
Once a property of a family is requested (such as its writing system,
style, etc), the family is lazily populated by calling back to the
platform database through QPlatformFontDatabase::populateFamily(),
which in turn does the final call to registerFont() as before.
This cuts application startup on OS X and iOS (of which the font population
used to be a major limiting factor) from roughly one second to about 350ms.

On Mac, hb_coretext requires both CTFont and CGFont.
Due to not supporting the 0 tag by CoreText, hb_blob_get_data()
always fails causing the hb_coretext_shaper initialization to fail, too.
Since HarfBuzz-NG is not a part of QtGui module anymore,
there are two possibilities to workaround this: either engineer the
font data by querying tables one-by-one and generating the font
directory table, or pass CTFont and CGFont refs directly to hb_coretext
via the hb_face's user_data. This patch implements the latter.

The font database and QFont should have normalized font family names,
so using CTFontDescriptorCopyLocalizedAttribute is not a good idea.
If the feature of reporting the localized name of a font family or
style is needed in for example the font selection dropdown or dialog,
it should be exposed as an explicit property of the font.

Populating the whole database takes a while, and it's very easy to trigger
the fallback family code path through eg. matching or getting the default
font family from QFont.
Instead of relying on populate to resolve family name to a PostScript name
(which was required when using CTFontCreateWithName), we instead use the
CTFontDescriptorCreateWithAttributes() function to create a descriptor
based on the family name, and then use CTFontCreateWithFontDescriptor().
The other way around, we use CTFontDescriptorCreateWithNameAndSize, and
then pull out the family name from the descriptor. The need for creating
a CTFont for private fonts (eg '.Apple Symbols Fallback') does not seem
necessary anymore, as tested on 10.7-10.9.
The disadvantage of creating font descriptors instead of re-using the
data computed by population is that we're doing the same work twice,
but the end result is making the font database more lazy, and the 80%
use-case is assumed to be that you're only interested in the fallback
of a small number of fonts, which means you don't want to populate all
of the fonts in the system (taking about 1100ms on the test system).
Looking up the fallback of a single family or style now takes about
15-25ms.

The platform font database is populated from QFontDatabase, through the
static initializeDb() function, whenever the font database determines
that the platform database has not been initialized (by checking if the
font database is empty).
There are other clients of QPlatformFontDatabase though, such as QFont,
which uses the platform font database to check for the default family.
The CoreText implementation of determining the default family relies
on data that is computed during font population, and hence does an
internal (self-triggered) populate.
To prevent repeated populates as a result of calling QFont::defaultFamily()
we guard the populate by a similar isEmpty() check as QFontDatabase does,
but to ensure that this check works in the case of an invalidated font
database, we need to propagate the font database invalidation down to
the platform font database.

Being a most significant method in the font API,
getSfntTableData() must behave in exactly the same way on all platforms.
Briefly, it must return true if the table exists in the font,
despite the other params, and always stores the table data length
in 'length' param, thus reporting the amount of bytes actually
needed to store the table data in a buffer.

Padding the bounding rect was not enough, as we failed to shift the glyph
accordingly so that it would end up in the center of the bounding rect.
We also didn't take subpixel-positioning into account, which may shift the
position of the glyph too far to the right to be within the image size that
we reserve.
There are still cases where the glyphs seem clipped compared to the same
text rendered with CoreText, but that's because we end up shaping the
text slightly differently, resulting in different subpixel positions
than what CoreText chooses.

wasting both memory and cpu cycles while drawing. AlphaMapBoundingBox

Windows still has an arbitrary +4 in the its drawGDIGlyph() which
means batching will not work on windows, but at least now
other platforms do not need to suffer.

This patch fixes two issues that prevented the application font related tests
of tst_QFontDatabase from passing:
* The code for creating the font descriptor after the registration of an app font
with file name using CTFontDescriptorCreateWithAttributes must create a dictionary
with kCTFontURLAttribute as key and the CFURLRef pointing to the on-disk file as
value. Unfortunately the code mixed up keys and values in the dictionary.
* Registration of app fonts within QFontDatabase itself on Windows and Fontconfig
platforms works by QFontDatabase calling addApplicationFont on the platform db
after calling populateFontDatabase(). It assumes that addApplicationFont on the
platform db is capable of registering the font right away. This part was also
missing from the Mac implementation and this patch implements it by moving the
common registration code from a CTFontDescriptorRef out into a separate method,
called from populateFontDatabase() as well as addApplicationFont().

CoreText segfaults when creating paths for color-glyphs:
0 0x00007fff8fd41e69 in TFont::FindColourBitmapForGlyph ()
1 0x00007fff8fd417ac in TFont::CreatePathForGlyph ()
2 0x000000010567d1af in QCoreTextFontEngine::addGlyphsToPath (...)
So we shortcut the code-path, since we don't support Emoji yet anyways.

Useful for not having to fall back to QPainterPath drawing when using
the raster engine with a retina screen (which has a 2x scale).

Some cruft had built up over time, and this is an attempt at cleaning up
the naming and use of these functions, and should not have any behavioral
effects.
The function supportsTransformations() has been renamed in QPaintEngineEx
to reflect its use, which is to decide if QPainter needs to pre-transform
the coordinates of the static text before asking the paint-engine to draw
it. The new name is requiresPretransformedGlyphPositions().
The OpenGL and CoreGraphics (Mac) paint engines keep their behavior of
not needing pre-transformed text, while the raster engine needs this
when using cached glyphs. The base-class implementation assumes that
all transforms that include a projection will need pre-transform,
which is also the case for the raster engine.
All decisions in the paint engines about whether or not to use the
glyph cache when drawing text are now deferred to the function
shouldDrawCachedGlyphs(), which has been refactored for the GL paint
engine(s) to share more logic. All implementations call the base
class implementation, which ensures that large font sizes will not
be cached. The raster engine will in addition ask the font engine
whether or not it can produce glyphs for the glyph-cache with the
given transform.
This is the only remaining instance of the supportsTransformations()
function, and will for all font engines except the CoreText engine
support affine transformations. The CoreText engine on the other hand
only supports translations (for now).
