This fixes a crash as we would need to make each context current before
calling ReleaseFramebuffers.

However this is totally unnecessary as only the current context can have
bound framebuffers.

This thing was starting a timer that re-starts itself forever, and when
the file it was watching changed, it would just assume the drawing
objects were still there (and the document, for that matter...)

We need to set scaling factors to device's map mode *only* for the texts.
Calc handles scaling for all the rest.  Interesting how it works.

With this, the tiles get rendered correctly at varying zoom levels.

ScRangeList::DeleteArea() may remove an entire range, if it was the
last range a subsequent call to ScConditionalFormat::DeleteArea() would
attempt to access an invalid first element.

This works well at 100% zoom, but the offsets are still not correct
at zoom levels other than 100%.

...as e.g. the read+write+exec arena used in
bridges/source/cpp_uno/shared/vtablefactory.cxx has specific requirements on
obtained memory.  This broke recent 8b9968a2
"fdo#72755: Only use double mmap as fallback" for e.g. --enable-ooenv (which
sets G_SLICE).  This is a partial revert of
ce906b80 "skip tricky allocators on
G_SLICE=always-malloc."

...when write+exec mmap fails (due to SELinux deny_execmem).  This avoids the
tmp file creation in environments that don't need it and which in turn have
problems of their own with that tmp file business.

An alternative would be to first check whether SELinux deny_execmem is enforced
and only then try double mmap first.  An advantage could be that it might avoid
false SELinux alerts in that case.  The disadvantage would be the overhead of
introducing a conditional dependency on libselinux here.  And given that for one
deny_execmem typically appears to be off by default (as at least both
contemporary GNOME desktop and OpenJDK malfunction when it is enabled), and for
another I guess deny_execmem could still change its value between the time of
checking for it and the time of requesting a write+exec mmap, that just does not
seem worth it.

So that the callback code running on the main thread can be aware of the
event type and payload (necessary in the future to do partial repaints).

With this, gtktiledviewer gets the proper invalidation rectangles after
keypresses.

When the invalidation callback is invoked, we call PaintTile() for each
tile that is affected by the invalidated rectangle. Make sure
PaintTile() doesn't result in new invalidations generated by itself,
to avoid infinite loops.

The primary purpose of gtktiledviewer is to see the same features / bugs
than on mobile devices. On Android we already render 256x256px tiles, do
the same in gtktiledviewer instead of a single huge tile.
