Patch for r600 GPUs
I have written a mod for the game Stellaris, which seems to fix this problem
for AMD GPUs that use the r600 driver.

The mod changes the pixel shader that creates the border. I simply manually
unrolled a loop and turned a function into a macro. There are no functional
differences and these changes should make no difference in the resulting code,
yet they make the shader work.
I don't know why it works and I am not an expert in this stuff, but I think
there could be a bug in the GLSL compiler. Maybe the register allocator messes
something up and manually unrolling the loop fixes it.
