This reverts commit 6fd71992. Kendy says the
original problem can't be reproduced anymore, and most unexpected flickering
goes away with this for my nvidia card.

Also, it's a good idea in general to keep PFD_DOUBLEBUFFER and
WGL_DOUBLE_BUFFER_ARB in sync, which is now the case.

Treat an array of null string pointers as no strings for OpenCL. For
some reason, at least in the case of the "Test OpenCL" thing, we got
an mpStringArray that is non-null but where all the elements
(rtl_uString pointers) in it are null. Treat that case as if the
mpStringArray was null.

This makes the tests "Test OpenCL" actually use OpenCL. Maybe it has other
useful effects, too. (But for normal spreadsheet use, the mpStringArray that
gets handled here *is* null when all the cells used by a formula group are
numbers. At least it seemed so in a simple test.)

Add a few more useful (?) SAL_INFO calls.

Some cosmetic changes to make the code look saner.

Return correct value from the OpenCL VLOOKUP implementation. Also,
when the lookup fails, produce the expected N/A error code instead of
a bare NaN.

Don't claim we support strings arguments in the OpenCL VLOOKUP.  The
string support certainly isn't complete or correct anyway. Partially
revert c3383aaf.

Add VLOOKUP to the set of opcodes that we trust the OpenCL
implementation for.

Turns out that in order to enable the GL_DEBUG_OUTPUT_SYNCHRONOUS_ARB
extension, the GL context must be created with WGL_CONTEXT_DEBUG_BIT_ARB
set. It seems that other drivers did not enforce this so far, but in
this case the driver just crashes without this.

Fix the problem by splitting out the debug setup part of InitGLEW() into
a new InitGLEWDebugging(), and at least on Windows call it only after
wglCreateContextAttribsARB() and wglMakeCurrent(). Additionally make
sure that in the debug case the necessary flag is passed to
wglCreateContextAttribsARB().

For each iteration of the (gtk) main loop we are dropping the yield
mutext which results in calling OpenGLContext::clearCurrent. That method
calls OpenGLContext::ReleaseFramebuffers which would call in the end
glBindFramebuffer for each framebuffer related to that context.

This would easily grow into the thousand OpenGL calls without doing any
work.

Many places were already adapted for the tiled rendering, and the conditions
checking for the VisArea() were changed so that the checks are ignored when
tiled rendering is active.

Unfortunately there are still some places left, and they are causing that
various areas are invalidated only partially.  Let's sort it out for good, and
report the entire document as the VisArea() when the tiled rendering is
active, and if there are performance problems, let's profile that & act
accordingly.

In the tiled rendering case, the desktop is headless, so the toolbar
is not created.  The toolbar usually initializes all UNO url commands
for each tool item attached.

This causes that SfxControllerItem that monitor a state, it is not
intercepted by InterceptLOKStateChangeEvent so no callback status changes.
