/**
*
* Immediate mode sink, implementing OpenGL fixed function subset of immediate mode operations, i.e.
*
* glBegin();
* glVertex3f(1f, 1f, 1f);
* glColor4f(1f, 1f, 1f, 1f);
* ...
* glEnd();
*
* Implementation buffers all vertex, colors, normal and texture-coord elements in their respective buffers
* to be either rendered directly via {@link #glEnd(GL)} or to be added to an internal display list
* via {@link #glEnd(GL, boolean) glEnd(gl, false)} for deferred rendering via {@link #draw(GL, boolean)}.
*
* Buffer storage and it's creation via {@link #createFixed(int, int, int, int, int, int, int, int, int, int) createFixed(..)}
* and {@link #createGLSL(int, int, int, int, int, int, int, int, int, int, ShaderState) createGLSL(..)}
*
* If unsure whether colors, normals and textures will be used,
* simply add them with an expected component count.
* This implementation will only render buffers which are being filled.
* The buffer growing implementation will only grow the exceeded buffers, unused buffers are not resized.
*
*
* Note: Optional types, i.e. color, must be either not used or used w/ the same element count as vertex, etc.
* This is a semantic constraint, same as in the original OpenGL spec.
