to create the thread for threadpool.
Creating the thread with WINE prevents some rarely occuring crashes.

st/nine: Don't present if window is occluded

The problem is that if one d3d present call fails,
because of our occlusion check in present method,
the next presentation call will send the same pixmap to the Xserver again,
without waiting it is released, which is wrong.

Move the present call after occlusion check to return and prevent
Xpixmaps errors.

st/nine: Implement IPresent version 1.2

Implement presentation interface version 1.2:
* ID3DPresent_ResolutionMismatch
    Poll for resolution mismatch.
    A third party app might have changed resolution,
    which requires a device reset.
* ID3DPresent_CreateThread
    Create a thread in WINE to allow nine to use Windows API
    functions. Required for multi-threaded presentation.
    In single-threaded presentation mode the calling thread is

st/nine: Add support for X8L8V8U8

X8L8V8U8 support should be common. Some more recent cards
do support this format, but not L6V5U5.

Add fallback for this format to have it alwaus supported.

L6V5U5 conversion rule apparently differs a bit from the normal
spec, and thus the gallium equivalent format leads to slightly
wrong colors. Since some recent cards do not support it, do not
support it either.
