#NOTE: Raspberry Pi and Cotton Candy do not use standard OpenGL.  Instead they use OpenGL ES 2.0

“For programmable hardware: OpenGL ES 2.0 is defined relative to the OpenGL 2.0 specification and emphasizes a programmable 3D graphics pipeline with the ability to create shader and program objects and the ability to write vertex and fragment shaders in the OpenGL ES Shading Language. OpenGL ES 2.0 does not support the fixed function transformation and fragment pipeline of OpenGL ES 1.x”
