After integrating the gst-plugins-gl shaders into piglit for regular parse
testing on Mesa, I found that 3 of them don't compile because they use GLSL
1.20 features (array constructors) without declaring #version 120.  The 1.30
spec is quite clear that without #version, then 1.10 is the version parsed. 
Current Mesa and the next Mesa GLSL parser both reject this code.  It's easy to
avoid the 1.20 requirement by expanding the array setup.

I implemented this fix, plus several improvements to gstglfilterblur's
implementation, in git://people.freedesktop.org/~anholt/gst-plugins-gl
