When the context is destroyed and recreated, we end up with a new glyph
cache, but we only recreate the vertex arrays for the very first static
text item. We need to keep track of the glyph cache in each text item,
so that we can recreate the vertex arrays and re-populate the cache
accordingly. As the pointer might be the same after the glyph cache is
recreated, we need to use serial numbers instead.
We also need to re-create the cache when the context pointer has been
invalidated, so that the static text items also get invalidated, and
the texture glyph cache gets repopulated.

Q_DECL_IMPORT is still __declspec(dllimport), which is unsuitable for
static code.
Commit edbc656b changed Q_DECL_IMPORT_IMPORT to Q_CORE_EXPORT when
declaring QtCore functions in svg.
Now we change Q_DECL_IMPORT to Q_GUI_EXPORT when declaring QtGui
functions into opengl and openvg.
Also removed the redundant keyword "extern" from the function declarations.

Change 532115bcaa370af827a5cbad017b272842c5aacf introduced a regression
by fixing a typo in the QT_OPENGL_ES_2 macro. This caused a broken
and untested code path to be used in the GLES2 case. Since the QImage
scanlines are 32 bit aligned, QImage::width() cannot be used when
copying the data. Rather than pass in bytesPerLine() to the GL function,
I opted to revert to the proven behavior, where the pad bytes are never
read by GL but each scanline is copied separately, to avoid further
regressions on different hardware. This also seems like the more correct
approach, as the pad bytes should ideally not be copied into the cache
texture.

To avoid calling the bounding box function for the same non-printable
characters in every call, we cache them as empty in the coords table
and bail out before painting them. This patch also fixes some possible
reads of uninitialized memory (reference to return value) and reference
to a default constructed object consisting of uninitialized pods.

It seems that copying small rectangles from glTexSubImage2D into a
texture which is 2048x2048 is busted on some SGX drivers, even though
the driver reports 2048 as the maximum texture size. This caused text to
turn into flickering garbage once the texture glyph cache had grown to
its max size (e.g. when painting very many Chinese glyphs.) To work
around the problem, we hardcore the maximum texture height to 1024 on
this driver so that the texture glyph cache is reset whenever that
size is exceeded.

Since scaled text is backed by an A8 glyph cache, it needs to repopulate
even if it has previously populated the cache for the unscaled text.
This means that we need to record in the userData that the type of the
cache is not the same as the last time. Otherwise the A8 version of the
cache will only be updated when it's created and when the text actually
changes, leading to glyphs missing on screen when zooming text using
a scale.

When there is no transformation on a glyph in the GL texture glyph
cache, it will take the RGB code path to support subpixel antialiasing.
In this code path we would ask glTextImage2D() to convert from a
GL_ALPHA buffer to an internal format of GL_RGBA. This is not supported
on OpenGL ES 2, and would cause missing text for some drivers.
The change also fixes a typo in an #ifdef.

When the OpenGL glyph cache filled up (the max texture size on the
hardware was exceeded) the characters would be drawn as black blocks
instead. As a work-around for this, the cache will now be cleared and
repopulated whenever this happens, meaning that once in a while (when
a lot of different glyphs have been drawn in a font) there will be a
performance hit. A more complete solution is described in QTBUG-13784,
but this requires so much refactoring that it was deemed too risky for
a patch release. This patch fixes the problem with a small penalty
and low risk.

If you create/destroy gl contexts a lot, you may sometimes get a new
context with the same pointer as a destroyed context. When you look up
the glyph cache in the font engine using the context pointer as a key,
you will then get a glyph cache which contains no valid data. We need
to reset the glyph cache completely in this case and set up bindings for
the new context so that the glyph cache can be repopulated and reused.
Note that there is a different solution for this in Qt 4.8, so this is
temporary solution for the Qt 4.7.x series.
