/**
* Native bindings to the ARB_transform_feedback_instanced extension.
*
* Multiple instances of geometry may be specified to the GL by calling functions such as {@link GL31#glDrawArraysInstanced DrawArraysInstanced} and {@link GL31#glDrawElementsInstanced DrawElementsInstanced}.
* Further, the results of a transform feedback operation may be returned to the GL by calling {@link GL40#glDrawTransformFeedback DrawTransformFeedback}, or
* {@link GL40#glDrawTransformFeedbackStream DrawTransformFeedbackStream}. However, it is not presently possible to draw multiple instances of data transform feedback without using a query
* and the resulting round trip from server to client.
*
* This extension adds functionality to draw multiple instances of the result of a transform feedback operation.
*
* Requires {@link GL40 OpenGL 4.0} or {@link ARBTransformFeedback2 ARB_transform_feedback2}. Requires {@link GL31 OpenGL 3.1} or {@link ARBDrawInstanced ARB_draw_instanced}. Promoted to core in {@link GL42 OpenGL 4.2}.
