isES() becomes isOpenGLES(). The library type enums are changed
DesktopGL -> LibGL and GLES2 -> LibGLES. This removes the now
unnecessary version number, the confusing "desktop" term and provides
better readability.
The old function/values are kept until the related qtdeclarative
changes are integrated.

This patch fixes an issue when a font that was added with
QFontDatabase::addApplicationFont can not be removed any more.
The reason for that is that QFontconfigDatabase::addApplicationFont
adds the font to the FontConfig application set from where it
cannot be removed any more and is picked up every time the font database
is repopulated (e.g. after a call to QFontDatabase::removeApplicationFont).
This also fixes the QFontDatabase autotest which unfortunately does
not fail on linux, because it tries to add "FreeMono" (which in most
cases is already there as a system font). So this patch removes FreeMono
and adds LED_REAL as test font.

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.

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.

Passing OpenGLES and majorVersion 3 in a QSurfaceFormat selects GLES3 in case
it is supported. This works fine already now, but is not safe since the config
choosing logic does not request a GLES3-capable configuration and so it may
end up with a non-GLES3 compatible one.
This is now corrected by passing the EGL_OPENGL_ES3_BIT_KHR bit when
EGL_KHR_create_context is available.

The UnicodeText converter is a bit special since it can convert
to both utf8 and utf16 for text/plain. But since flavorFor("text/plain")
can only return one UTI, it returns utf16. And this means that
canConvert will return false if given utf8 as argument.
On iOS this is often the only format available on the pasteboard, which
means that pasting text from another app app will fail.
This patch will ensure that it returns true for both utf8 and
utf16.

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.

Remove the opengl proxy for now. Later it will either be moved into
a separate library or replaced by a QOpenGLFunctions-based approach.
This means that the -opengl dynamic configuration is not usable
for the time being. The rest of the enablers remain in place.
The convenience function QOpenGLFunctions::isES() is now moved to
QOpenGLContext and is changed to check the renderable type. This is
extremely useful since besides supporting dynamic GL it solves also
the problem of GL_ARB_ES2_compatibility (i.e. it triggers the real ES
path when creating an ES-compatible context with a desktop OpenGL
implementation).

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.

The Origin for Target rect was deemed a confusing concept. The current
implementation would translate the target rect to the coordinate system
specified. However, the order and "direction" of the vertices would
always be the same. So drawing a texture in for one target rect defined in
one coordinate system would paint the texture the same way as it would
when a texture was drawn for a target rect drawn in the "opposite"
coordinate system. The point with this was that if you wanted to "flip"
the texture you would specify that with the source coordinate system.
However, this approach breaks on different levels, such as QRect has functions
which expects a top left coordinate system (ie. top() and bottom()).
In the end Qt uses a top left coordinate system, hence QWindow specifies
a top left coordinate system, and hence the api becomes easier if it is
not possible to define the coordinate system of the target viewport.

Moving them into QPlatformDialogHelper for the convenience of both
widgets and QtQuick.Dialogs. The main reason is to ensure that
QtQuick.Dialogs does not need to depend on the widgets module, in
order to re-implement the button box concept in a generic dialog.

The patch introduces a new build configuration on Windows which
can be requested by passing -opengl dynamic to configure.
Platforms other than Windows (including WinRT) are not affected.
The existing Angle and desktop configurations are not affected.
These continue to function as before and Angle remains the default.
In the future, when all modules have added support for the dynamic
path, as described below, the default configuration could be changed
to be the dynamic one. This would allow providing a single set of
binaries in the official builds instead of the current two.
When requesting dynamic GL, Angle is built but QT_OPENGL_ES[_2] are
never defined. Instead, the code path that has traditionally been
desktop GL only becomes the dynamic path that has to do runtime
checks. Qt modules and applications are not linked to opengl32.dll or
libegl/glesv2.dll in this case. Instead, QtGui exports all necessary
egl/egl/gl functions which will, under the hood, forward all requests
to a dynamically loaded EGL/WGL/GL implementation.
Porting guide (better said, changes needed to prepare your code to
work with dynamic GL builds when the fallback to Angle is utilized):
1. In !QT_OPENGL_ES[_2] code branches use QOpenGLFunctions::isES() to
differentiate between desktop and ES where needed. Keep in mind that
it is the desktop GL header (plus qopenglext.h) that is included,
not the GLES one.
QtGui's proxy will handle some differences, for example calling
glClearDepth will route to glClearDepthf when needed. The built-in
eglGetProcAddress is able to retrieve pointers for standard GLES2
functions too so code resolving OpenGL 2 functions will function
in any case.
2. QT_CONFIG will contain "opengl" and "dynamicgl" in dynamic builds,
but never "angle" or "opengles2".
3. The preprocessor define QT_OPENGL_DYNAMIC is also available in
dynamic builds. The usage of this is strongly discouraged and should
not be needed anywhere except for QtGui and the platform plugin.
4. Code in need of the library handle can use
QOpenGLFunctions::platformGLHandle().
The decision on which library to load is currently based on a simple
test that creates a dummy window/context and tries to resolve an
OpenGL 2 function. If this fails, it goes for Angle. This seems to work
well on Win7 PCs for example that do not have proper graphics drivers
providing OpenGL installed but are D3D9 capable using the default drivers.
Setting QT_OPENGL to desktop or angle skips the test and forces
usage of the given GL. There are also two new application attributes
that could be used for the same purpose.
If Angle is requested but the libraries are not present, desktop is
tried. If desktop is requested, or if angle is requested but nothing
works, the EGL/WGL functions will still be callable but will return 0.
This conveniently means that eglInitialize() and such will report a failure.
Debug messages can be enabled by setting QT_OPENGLPROXY_DEBUG. This will
tell which implementation is chosen.
The textures example application is ported to OpenGL 2, the GL 1
code path is removed.
[ChangeLog][QtGui] Qt builds on Windows can now be configured for
dynamic loading of the OpenGL implementation. This can be requested
by passing -opengl dynamic to configure. In this mode no modules will
link to opengl32.dll or Angle's libegl/libglesv2. Instead, QtGui will
dynamically choose between desktop and Angle during the first GL/EGL/WGL
call. This allows deploying applications with a single set of Qt libraries
with the ability of transparently falling back to Angle in case the
opengl32.dll is not suitable, due to missing graphics drivers for example.
