Reviewed by Martin Robinson.

Source/WebCore:

Removed TextureMapperQt, and instead created a TextureMapperImageBuffer class,
which responds to an "Software" mode of TextureMapper, instead of creating subclasses
of TextureMapper directly. This allows using the software fallback of TextureMapper by any
sort.

To make the ImageBuffer backend easier, content updates to BitmapTexture can now use either
an image, or a raw data pointer. The raw data pointer is provided for performance reasons,
as converting data to/from Image references in Qt generates unnecessary deep copies of the
image data.

Also, functions that use TransformationMatrix were added to GraphicsContext, to allow for
3D transforms in cross platform code.
After this patch everything renders the same. An additional bug report was created to allow
ImageBuffer shallow image copies: https://bugs.webkit.org/show_bug.cgi?id=77689

Covered extensively by existing tests, no behavioral changes.
