Module context

To Do:

• Provide convenience setters for glBlendFunc via blend_func=("SRC_ALPHA", "ONE_MINUS_SRC_ALPHA").
• Add listing of all bound textures, buffers, etc.
• Do we need indexed variants for glEnable?
• Wrap glPatchParameter.
• Implement multiple viewports using glViewportIndexed, glViewportArray, glScissorIndexed, and glScissorArray.
• Wrap glSampleCoverage, glSampleMaski, glMinSampleShading, GL_SAMPLE_COVERAGE_VALUE, and GL_SAMPLE_COVERAGE_INVERT.
• Wrap glReadPixels and related framebuffer copy functions.
• Add indexed getters for GL_TRANSFORM_FEEDBACK_BUFFER_START, GL_TRANSFORM_FEEDBACK_BUFFER_SIZE, GL_UNIFORM_BUFFER_SIZE and GL_UNIFORM_BUFFER_START.
• Add getters for GL_CLIP_DISTANCEi, GL_DEPTH_CLAMP, GL_FRAMEBUFFER_SRGB, GL_MULTISAMPLE, GL_PRIMITIVE_RESTART, GL_TEXTURE_CUBE_MAP_SEAMLESS, GL_SAMPLE_ALPHA_TO_ONE, GL_SAMPLE_ALPHA_TO_COVERAGE, GL_SAMPLE_COVERAGE, GL_SAMPLE_SHADING, and GL_SAMPLE_MASK.
• Implement stencil buffers using GL_STENCIL_BACK_FUNC, GL_STENCIL_FUNC, GL_STENCIL_BACK_REF, GL_STENCIL_REF, GL_STENCIL_BACK_VALUE_MASK, GL_STENCIL_BACK_WRITEMASK, GL_STENCIL_VALUE_MASK, GL_STENCIL_WRITEMASK, GL_STENCIL_BACK_FAIL, GL_STENCIL_BACK_PASS_DEPTH_FAIL, GL_STENCIL_BACK_PASS_DEPTH_PASS, GL_STENCIL_FAIL, GL_STENCIL_PASS_DEPTH_FAIL, GL_STENCIL_PASS_DEPTH_PASS, etc.
