Some OpenVG GPU's have limitations on the amount of memory
available to create VGImage's. When the memory runs out,
vgCreateImage() will fail.
This change introduces QVGImagePool, which keeps track of all
QVGPixmapData image allocations and ejects least-recently-used
pixmaps when GPU memory is exhausted.

If vgCreateImage() runs out of memory, then the drawPixmap()
will fail. But previously, it would also prevent future attempts
to call vgImageSubData() to populate the data when memory was present.

Under S60, Qt will destroy the window surfaces of an application that
goes into the background, which frees up EGL surface objects. But the
VGImage's for pixmaps, and the EGLContext, were still using GPU memory.
This change keeps track of the number of widgets / window surfaces that
are in use and then calls hibernate() on all QVGPixmapData objects when
it goes to zero. Once all the VGImage's are destroyed, the EGLContext
should also be destroyed.

When a complex transform was set, clip(QVectorPath) would call
clip(QRect) with the control point rect, which would then turn
around and say "transform is complex, call clip(QVectorPath)",
causing an infinite loop until stack crash. Remove the "fall back
to vector path" case as it isn't useful for scissor-only clipping.
Doesn't affect mask-based clipping.

Previously, the composition helper would use the VG window surface
private structure to get the VGImage to blit. This change passes
the VGImage and size values in directly so that the composition
helper can also be used to blit GL surfaces that have been converted
into a VGImage via an EGLImage.

When a pixmap's contents change in QVGPixmapData, only recreate

Previously, the drop shadow was colorizing the incoming
image and then blurring the colorized version. This change
first blurs the image to an alpha-only VGImage and then uses
that VGImage as a stencil to draw the drop shadow color.
This way, there is only 1 filter step and a draw instead of
2 filter steps and a draw. The result is to make the performance
of the drop shadow filter almost identical to the blur filter.

Custom window surfaces, graphics systems, and Qt/Embedded screen
drivers often need to access QPaintDevice::metric(), but it is
protected. Hence the growing number of friends in QWidget and
QImage. The qt_paint_device_metric() function provides a more
future-proof approach that doesn't require lots of friends.

It wasn't possible for the paint engine to override the drop
shadow filter because QPixmapDropShadowFilter::draw() was not
asking for an engine-specific filter object.
Also, change the OpenVG filter to use vgGaussianBlur() instead of
vgConvolve(), and draw the original image on top of the shadow.

The QPF implementation of alphaMapForGlyph() was returning
color values of RGBA = (a, a, a, 255) instead of (0, 0, 0, a),
which was inconsistent with all the other font engines.
This inconsistency caused some QPF-specific workarounds in the
OpenGL and OpenVG paint engines. This change removes the workarounds
and makes QPF generate the right colors from the start. Paint
engines that ignore the color table or which don't use the
alphaMapForGlyph() function (e.g. raster) are not affected.

QtOpenVG was doing a lot of housekeeping to avoid having to
switch EGL contexts if the same surface was used over and over.
This housekeeping really belongs in the QEgl layer so that
QtOpenGL could potentially use it as well.
This change also adds some overrides for makeCurrent(),
swapBuffers(), and destroySurface() that take an EGLSurface
directly. This is the first step in separating EGL surface
management from context management.

We can delay calling ensureContext() since it will happen when painting
begins anyway. There is a chance that we can get to this function when
a window is being hidden and if this is the first thing that happens in
the application, there is no need to call ensureContext() yet.

We need a way to support converion to and from multiple native pixmap
types from multiple pixmap backends. Instead of adding more virtual
functions to QPixmapData, make the existing one more generic but pass
an opaque pointer and a type and do some internal casting.
Currently this function is Symbian only, but could easily be extended
to work on other platforms.

Engine-specific pixmap filters were being created, used, and destroyed
every time draw() was called on QPixmapColorizeFilter, QPixmapBlurFilter,
and so on. This had a heavy performance penalty and made it difficult
for the GL paint engine to cache shaders from one request to the next.
A generic filter can request an engine-specific filter that matches its
parameters. The engine can either create a new one or return a previously
allocated filter object.
Ownership of engine-specific pixmap filter objects is moved to the
paint engine itself.
