[Pixman] [PATCH] Fixing the runtime error in VS debug build under Windows.

[Gang Ji]

Hi everyone,

We have met a run time crash when using a debug VS build under Windows due
to potential of using an uninitialized variable.  By looking at the code,
max_vx could also be an uninitialized value.  The fix is to initial that
variable to 0.  The version we are using is 0.21.4.

Thanks,
Gang
