So that when the document changes, they can know what tiles to throw
away.

... when the callback is invoked

So that LOK clients can invoke the new
vcl::ITiledRenderable::registerCallback().

This way subclasses may know when and what is invalidated.

This can be overriden in applications, if they need a callback.

A follow-up on 09a5910c
move nScanLineBufferComponents to where it is used [-Werror=clobbered]

If pScanLineBuffer is used, nScanLineBufferComponents is the
corresponding counter so it needs to be preserved as well in case of a
longjmp.

    fdo#38844 Reduce XOR clipping for gradients

    Removed XOR clipping version of ClipAndDrawGradientMetafile. Because it
    has been removed, the other version isn't really needed in it's own
    function so I've moved it back into DrawGradient.

This should make OpenGL thread-safe to allow multiple threads to
render using VCL's OpenGL backend, and fix misc. associated driver
horrors, will give some performance cost for tight Yield loops.
