[Piglit] default piglit window size change

[Brian Paul]

I think I've brought this up in the past.  On Windows, the minimum 
width of a window is 116 pixels (at least in my current Win7 setup). 
A lot of piglit tests create 100x100 pixels and when piglit creates 
the window, Win7 resizes it to 116x100.  The framework code detects 
this change and reports:

Got spurious window resize in automatic run (100,100 to 116,100)
PIGLIT: {'result': 'warn'}

So a bunch of tests get the 'warn' result instead of being run 
properly.  I think this changed at some point during the recent 
framework/waffle overhaul.

My proposal for this is to set a default window size of 150x150 in the 
piglit-framework-gl.h header:

         \
+                config.window_height = 150;

  #define PIGLIT_GL_TEST_CONFIG_END 
          \


And then remove these config lines from a bunch of tests:

        config.window_width = 100;
        config.window_height = 100;

Of course, I'll have to inspect these tests to make sure they don't 
rely on that specific window size, but I bet few if any of them do.

This change fixes things here.

Sound OK?
