Title: 26-gpgpu-3 : Wave Eqn : Descriptive text differs from Model answer

Update glsl to match README.md, which seems to have appropriate dimensions
Fixes issue #76

Hope this makes sense

PS: Without the change, the 'incorrect' version of the wave eqn also VERIFIES Ok, except that they can be seen to be different using the 'slider'.
