GlProgram(handle: Int)
GlProgram(vertexShader: String, fragmentShader: String)
GlProgram(vararg shaders: GlShader) protected GlProgram(handle: Int, ownsHandle: Boolean, vararg shaders: GlShader)

Base class for a program that accepts a vertex and a fragment shader in the constructor. The program will be created automatically and released when release is called.

Subclasses are required to do two things - typically, during the onPreDraw callback: 1 Inspect the GlDrawable properties:

GlDrawable.vertexArray
GlDrawable.coordsPerVertex
GlDrawable.vertexStride These should be passed to the vertex shader. 2 Pass the MVP matrix to the vertex shader as well.

The vertex shader should then use the two to compute the gl_Position.
