d42a9d19ff Remove tst_QGLThreads::textureUploadInThread
The test has been crashing flakily recently.

   1) It is creating a QGLWidget
   2) It is stealing the QGLContext of that widget and moves it into a separate
      thread.
   3) In that secondary thread it makes the context current.
   4) Meanwhile the QGLWidget itself may receive for example a resizeEvent or
      other events and - since it assumes that it owns the context - attempts to
      make it current.
   5) Attempting to call makeCurrent() on a QGLContext that is in a different
      thread than the current thread (via QObject thread affinity) will result
      in a call to qFatal() and consequently the test aborts.

The conclusion from Simon Hausmann is that this test is testing a pattern from
Qt4 times that may or may not have worked back then. Nowadays with the Qt5
QOpenGL* API we do support this properly and there appears little sense testing
this.

Therefore remove the test altogether.

19b0ce5daa Change almost all other uses of qrand() to QRandomGenerator
The vast majority is actually switched to QRandomGenerator::bounded(),
which gives a mostly uniform distribution over the [0, bound)
range. There are very few floating point cases left, as many of those
that did use floating point did not need to, after all. (I did leave
some that were too ugly for me to understand)

This commit also found a couple of calls to rand() instead of qrand().

This commit does not include changes to SSL code that continues to use
qrand() (job for someone else):
  src/network/ssl/qsslkey_qt.cpp
  src/network/ssl/qsslsocket_mac.cpp

64bce9bbff tst_QGL::graphicsViewClipping: Wait for viewport's window handle
The QWidget overload of qWaitForWindowExposed waits for the widget's
top level QWindow, which for the viewport is the graphics-view.

We want to explicitly wait for the viewport to be exposed, as the
viewport is covering the whole graphics-view, preventing it from
being exposed. See a6991376c.

dd38574160 Switch to RGB(A|X)8888[_Premultiplied] for QOpenGLFBO readbacks on GLES
Instead of the never-ending blacklisting of "broken" drivers, simply switch
to always choosing a byte ordered QImage format with OpenGL ES, and keep
on using the (one and only) spec-mandated GL_RGBA/GL_UNSIGNED_BYTE combo.

There is nothing broken with not supporting BGRA for glReadPixels even when
GL_EXT_read_format_bgra (an out of date, pre-2.0 extension that got folded
into the spec to begin with) is present. We do not have a good way to tell
if BGRA_EXT is supported for glReadPixels or not, so just skip the whole
problem altogether.

7dc88b6890 Add support for OpenGL 3.2+ core profile contexts in QPainter
This change allows painting via QPainter onto a QOpenGLWindow, QOpenGLWidget
or QOpenGLFramebufferObject when an core profile context is in use. This is
important on macOS in particular, where compatibility profiles are not
available, and so the only way to use modern OpenGL is via a core profile
context.

Added core profile compatible shaders with moder GLSL keywords.

The paint engine binds a VAO and two VBOs from now on, whenever VAOs are
supported. Note that this changes behavior also for OpenGL 2.x context that
have VAO support via extensions.

The Lancelot test suite gains support for core profile contexts. This can
be triggered via -coreglbuffer in place of -glbuffer when manually inspecting
via 'lance', while tst_lancelot will automatically run core context-based tests
whenever supported.

6a35e77ef3 Change confusing Q_DEAD_CODE_FROM_QT4_FOO define
Commit c5db8fc74 changed all instances of Q_WS_FOO to have the prefix
Q_DEAD_CODE_FROM_QT4 instead, to make it clearer when reading the code
that the code in question was a left-over from Qt4, when we used
Q_WS_ defines instead of Q_OS_ defines.

This worked well for cases of #ifdef Q_DEAD_CODE_FROM_QT4, but less so
for cases of #ifndef Q_DEAD_CODE_FROM_QT4, where the code was actually
unconditionally included.

To make this even clearer, the defines have been replaced by checks for
1 or 0, with a comment describing how the code used to look in Qt4. The
use of constants in the check also makes it easier for editors to parse
the condition and show visually that the code is defined out.

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.

4b2f35d04c Dynamic GL: remove exporting symbols
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).

97c187da3c Dynamic GL switch on Windows
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.

bd5cea5ba8 Resurrect QGLWidget::renderPixmap()
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.
