Set gl_Position if it's missing in vertex shader #472

Closed GoogleCodeExporter closed 9 years ago

Apparently spec allows this, but with undefined behavior.

However, some drivers (for example, NVIDIA linux driver) will fail.

So we will issue gl_Position = vec4(0.0, 0.0, 0.0, 1.0); if it's not set in the 
vertex shader.

Note: please cover this under a compilation flag so that it can be turned off.
