Blur ported to GLES.
...
It now uses a GLShader for GLSL shaders and pushes it using the
ShaderManager.
It does not work with the nouveau driver plus GLES, but it works
with fglrx + desktop GL 2.x, so I assume it is a driver problem here.

Use GL_CONSTANT_ALPHA instead of reducing the opacity in the fragment shader.
...
This makes the blending work correctly when the alpha bits are zero,
which is apparently the case with NVidia.
