Shaders

[Timo 6]

In order to get shaders working on my system, I have had to change fragment.glsl in lightaccumulate and logluminance. The log from before this is here: http://pastebin.com/bug8Fa8f
These are the changes I made:
Line 128 lightaccumulate: vec3 ref_sharpish = textureCube(tu4_cube, refmapdir, reflection_lod).rgb;
Line 24 logluminance: gl_FragColor.rgb = vec3(1.,1.,1.)*texture2D(tu0_2D, tu0coord, lod).r;
This got shaders working, but still with errors: http://pastebin.com/F2HcyxBM
I was wondering if this is just my computer (the intel graphics maybe) and so I should revert the changes before releasing as it will break stuff for others, or if it's alright to check the changes into SVN.
