When Convolution matrix meets KGLShader

Today I have implemented Matrix Convolution as a shader for KGL. Matrix convolution is an easy way to create simple effects with a simple matrix computation.
For example, you can use it in Gimp.
But the difference between Gimp and KGL, is so important. Gimp use the CPU and KGL use the GPU thanks shaders! So, now you can easily make realtilme animation with convolution effects what can not do CPU.
Thanks olivier gueudelot for the idea!

So , look this :
Normal Texture {0,0,0, 0,1,0, 0,0,0}


Contrast effect {0,-1,0, -1,5,-1, 0,-1,0}


Border detection {0,1,0, 1,4,1, 0,1,0}


Random Value ( I don't remeber the matrix :))


Blur effect {1,1,1, 1,1,1, 1,1,1}


Bump effect {-2,-1,1, -1,1,1, 1,1,2}
