When using QGLWidget in combination with QOpenGLFramebufferObject from
QtGui, instead of QGLFramebufferObject from QtOpenGL, the current_fbo
variable doesn't get updated when framebuffer object bindings change.
To ensure that the QGLWidget correctly releases the currently bound
framebuffer object when using a QPainter, we keep track of whether
QOpenGLFramebufferObject has modified the current FBO binding, and if
that's the case we need to read the OpenGL state directly instead of
relying on a cached value.

During the Qt 4 -> 5 migration the setting of the extension flags
in QOpenGLFunctions/Extensions suffered a regression: flags like
GenerateMipmap were never set. This led to the unfortunate sitation
that features that were tied to these flags, like compressed texture
support or mipmap generation, got disabled.
This is now corrected by checking for the extensions like Qt 4 did.

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).

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.

This function has been completely broken since Qt 5.0. Unfortunately
the autotest's verification steps were somewhat faulty so returning
a null pixmap from renderPixmap() did not trigger a failure.
The implementation is now done with framebuffer objects and pixel
readback. This is not ideal performance-wise, but is the only option.
In Qt 4 pixmaps were often backed by platform dependent native pixmaps
that could be used as rendering targets for OpenGL content. This is not
an option anymore since pixmaps are raster backed on all the major platforms.

Default-constructed geometry does not mean put the window at 0,0,
and it does not mean center the window on the screen: it means
let the window manager position the window. If the window is
explicitly positioned at 0,0 though, that is a higher priority
than the transient hint; without this change, the transientFor property
had no effect. On X11, transient means use center "gravity" to
make the transient window exactly centered. But the user can still
override the geometry of a transient window, as with any window.
On OSX and Windows, neither transient window functionality nor smart
initial positioning are provided, so a window with no position set
will be centered on the screen, and a transient window will be put
at the center of its transientParent.

Since QtOpenGL/QGLContext is implemented in terms of
QtGui/QOpenGLContext which has stricter requirements about how it's
supposed to be used, we need to apply these requirements to QGLContext
as well.
This change adds QGLContext::moveToThread(QThread *) and documents it as
a necessity for making a context current on another thread.
Also introduces QGLPixelbuffer::context() to access the QGLContext of a
pixelbuffer, and made QGLWidget::context() return a non-const
QGLContext, since there's no good reason why it shouldn't, and it leads
to less const_cast clutter.
We could have introduced a backdoor in QOpenGLContext instead, making it
loosen its requirements, but that would have made it harder / impossible
to fully support threaded OpenGL in all the platforms.

The main reasons for doing this are:
1. _qpa.h end up in the master QtGui include file. QtGui is meant for
userland applications. qpa code is neither binary nor source compatible.
Inadvertant use of QPA api makes the user code binary-incompatible.
2. syncqt creates forwarding headers for non-private header files. This
gives people the impression that this is public API.
As discussed on the mailing list, even though QPA api is internal and subject
to change, it needs to treated differently from private headers since they
will be used by in-qtbase and out-of-qtbase plugins.
This commit does the following:
1. The _qpa in QPA header files is dropped.
2. syncqt now treats any file with qplatform prefix as a special file and
moves it to qpa/ directory. The recommended way of using QPA API in plugins
is: #include <qpa/qplatformfoo.h>. This allows the user include QPA API
from multiple modules (for example, qplatformfoo might be in QtPrintSupport)
3. The user needs to explicitly add QT += <module>-private to get access to
the qpa api.
4. Creates compat headers for the olden style qplatformfoo_qpa.h and QPlatformFoo
includes.
This commit does not change the cpp filenames. This requires a more careful
merging of existing non qpa cpp files and existing cpp files on a case by
case basis. This can be done at anytime.
The following files are not renamed as part of this changed but will be fixed
as part of a future change:
src/gui/kernel/qgenericpluginfactory_qpa.h
src/gui/kernel/qgenericplugin_qpa.h
src/gui/kernel/qwindowsysteminterface_qpa.h
files were renamed using
for x in `find . -name "qplatform*_qpa.h"`; do git mv $x "${x/_qpa.h/.h}"; done
