OpenGL test code
Generates a texture using the same initialization values from OpenCL stencil code, normalized
to RGBA values where low vales (upper left of matrix) are blue, and large values (lower right)
are red. Two triangles are created to create a rectangular object, and the generated texture is
then applied using shaders and displayed in the window.

Next step -> CL/GL buffer sharing to compute values from texture buffer using CL and re-display
using same procedure in GL.
