This patch provides a code generator that can be executed offline
to generate a few classes for enhancing Qt's support for OpenGL.
The generated code effectively provides all the benefits of GLEW
in its multi-context form but for all platforms and even for ES2.
The code generator takes as input the official Khronos gl.spec
specification and gl.tm typemap files. These provide all of the
information required to create the OpenGL Desktop related classes.
The classes for ES2 are hand-crafted as no similar spec files have
been published.
The generated code supports all OpenGL extensions listed in the
Khronos registry for both Desktop OpenGL and ES 2.
There is a helper factory class generated which are used by
QOpenGLContext::versionFunctions().
This allows code like the following to be written:
QOpenGLFunctions_3_3_Core* m_funcs = 0;
m_funcs = m_context->versionFunctions<QOpenGLFunctions_3_3_Core>();
if (!m_funcs) {
qWarning() << "Could not obtain required OpenGL context version";
exit(1);
}
if (!m_funcs->initializeOpenGLFunctions()) {
qWarning() << "Failed to resolve entry points";
exit(2);
}
// Get an extension object
QOpenGLExtension_ARB_draw_buffers* ext = 0;
if (m_context->hasExtension("GL_ARB_draw_buffers")) {
ext = new QOpenGLExtension_ARB_draw_buffers();
ext->initializeOpenGLFunctions(m_context);
}
Such usage will allow much easier and rigorous use of features in
modern OpenGL and extensions both in Qt itself and by users of Qt.
Follow-up patches will import the generated files and then use
these to reinstate OpenGL geometry shaders, add tessellation
shaders, and other OpenGL constructs.

In order to preserve the existing behavior, we map all scripts up to Latin to Common.

...where the values are not aliased to Common script.
The old QUnicodeTables::Script enum was retained for compatibility reasons
until Qt internals are updated to use QChar::script().
Using QChar::Script instead of QUnicodeTables::Script would improve both
the text analysis (itemization, boundary finding) and the text shaping quality.
This also a required step for switching to Hurfbuzz-NG.

The implementation of the various qHash overloads offered by
Qt can change at any time for any reason
(speed, quality, security, ...).
Therefore, relying on the fact that qHash will always give
an identical result across Qt versions (... across different
processes, etc.), given identical input, is wrong.
Note that this also implies that one cannot rely on QHash
having a stable ordering (even without the random qHash seed).
For such use cases, one must use f.i. a private hash function
that will never change outside his own control.
This patch adds a private hash function for QStrings,
which is identical to the Qt(4) qHash(QString) implementation.
A couple of spots in Qt where the results of a qHash call were
actually saved on disk are ported to use the new function,
and a bit of documentation is added to QHash docs.
