Currently the Qt Quick module depends on either the OpenGL or OpenGLES
headers being available at build time. Since we are adding support for
adaptations that do not depend on OpenGL, it should be possible to build
Qt Quick in environments that do not have OpenGL development headers.
This does present many challenges though because in some cases GL types,
and classes that require OpenGL are part of the public APIs. However
since these classes were never available when QT_NO_OPENGL was defined,
it should be possible to redefine the function signatures under this
scenario, since it's not possible to break binary compatibility if there
never were any binaries to break compatibility with.
One of the bigger changes that was necessary to facilitate this change
is creating interfaces out of QSGContext and QSGRenderContext. Here the
default behavior was usage of OpenGL directly, even though subclasses
could override all OpenGL usage. Making them interfaces should bring
QSGContext and QSGRenderContext more in line with the other classes
present in the adaptation layer.

Enablers for native text rendering. Distance field support is postponed
for the time being.
The main feature here is the revised texture handling where it is now
possible to schedule the update of multiple sub-regions from a list of
QImages. BGRA is now used where appropriate, meaning for example that
RGB32 needs no QImage conversion anymore.
The skeletons of the glyph nodes, the basic text material and the glyph
cache are added as well.
Also fixes cleanup when closing the window by properly reimplementing
invalidate() in the rendercontext.
The default rectangle, image and glyph nodes are refactored a bit once
again: QSGBasicSomethingNode is now the common (albeit optional), abstract
class, living in its own file, whereas QSGDefaultSomethingNode is the
GL-specific one, like before. This prepares the future renaming for
QSGDefault -> QSGOpenGL.
