[Bf-committers] glsl bugfix patch

[Fredrik hansson]

just added a patch that fixes some small issues with the glsl shader preview

http://projects.blender.org/tracker/?func=detail&aid=18928&group_id=9&atid=127

it fixes these 3 issues
1. texture nodes didn't output the alpha in glsl
2. material nodes didn't take input values for color spec normal...
3. the geometry node front/backface always returned 1
