Use vgWritePixels, if possible, in case where VGImage
for QPixmap can't be allocated due to low GPU memory
situation. This patch also renames some VG paint engine
internal functions to clarify their purpose.

QPainter has now gotten a drawPixmapFragments() function together
with a Fragment class that describes how each pixmap fragment is
supposed to be drawn.

Make the OpenVG code for QStaticText compile.

Done in the blind, so I don't expect this to compile, but it's to make
it easier to get it over into a Symbian-ready repository.

Best performance will be acheived with OpaqueHint and drawing
the full pixmap rather than sub-regions.

Previously rounded rectangles were converted into a QVectorPath
and then a VGPath. This change creates the VGPath directly without
an intermediate step and was made possible by change dd3e4308.

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.

Previously we were using QPaintEngine::syncState() which is not ideal
naming-wise, since it actually prepares for native painting instead of
syncing the painter's state to native state.

This change should improve performance of single-rectangle clip regions
by avoiding the overhead of creating and intersecting QRegion objects.

This change also moves the EGL support classes from QtOpenGL to QtGui
so they can be shared between OpenGL and OpenVG.
