Make sure that QOpenGLPaintDevice supports it the same way as
QGLPaintDevice::ensureActiveTarget dit. It is made virtual since the
external code needs to manage FBOs for QOpenGLPaintEngine.

Required changes for using shared graphics cache for distance field
raster glyph rendering. Most of the logic is in platform plugins.
Platform plugins should implement
QPlatformIntegration::createImagePaintEngine() to create a subclass
of QRasterEngine.

As in the past, to avoid rewriting various autotests that contain
line-number information, an extra blank line has been inserted at the
end of the license text to ensure that this commit does not change the
total number of lines in the license header.

glyphMargin() support for QTextureGlyphCache is implemented in
respective font engines, thus this function is platform dependent.
Before Qt 5 the code is guarded in macros like #ifdef Q_WS_MAC,
now we should move them into QFontEngine and its subclasses.
So far only Windows font engines support it. FreeType and Core Text
based font engines all ignore it.

We're trying to deprecate these, so don't use them anymore.
The inline uses of these have been left intact, for the moment. Inline code will
need to create their own non-inline allocation methods (for future-proofing to
allow alterations in how e.g. individual containers allocate)

Move subpixelPositionForX from QTextureGlyphCache to QFontEngine,
since some font engines like QFontEngineFT may need a custom
implementation or tweak it a little bit.
In QRasterPaintEngine::drawCachedGlyphs, do not add aliasedCoodinate
to x offset as that will break subpixel positioning.

ES 1.0 didn't have glTexParameteri, which is why we sometimes used
glTexParameterf. However, we shouldn't use glTexParameterf because
that's treating integer values as floating point, which is not type
safe. ES 1.1+ and ES 2.x have glTexParameteri, and we don't really care
about supporting ES 1.0 in any case in Qt 5.

This is simpler than the existing texture cache in QtOpenGL, as it only
serves the GL paint engine. There's one per context group, to simplify
the design and to prevent performance degradations.

The new API is more flexible, allowing the use of QOpenGLPaintDevice
with any QOpenGLContext, and putting more responsibility on the user for
ensuring the correct FBO is current (the user knows best anyhow).
