[compiz] blur plugin and GL_ARB_fragment_program extension
The blur plugin has GL_ARB_fragment_program extension as a prerequisite. At least that's what I'm getting by looking at screen.c. I think there should be a check for the "CompScreen::fragmentProgram" flag somewhere in blur.c to prevent it from loading or at least executing a <null> pointer. I get a crash in line blur.c:1858, because CompScreen::programEnvParameter4f is zero. I have a NV28 with 1.0-9631 binary drivers and a rv250 with Xorg7.1 drivers, none of which have the above extension. thanks PS: compiz from today's git version
