/**
* Native bindings to the EXT_base_instance extension.
*
* This extension allows the offset within buffer objects used for instanced rendering to be specified. This is congruent with the {@code first} parameter
* in glDrawArrays and the {@code basevertex} parameter in glDrawElements. When instanced rendering is performed (for example, through
* glDrawArraysInstanced), instanced vertex attributes whose vertex attribute divisors are non-zero are fetched from enabled vertex arrays per-instance
* rather than per-vertex. However, in unextended OpenGL ES, there is no way to define the offset into those arrays from which the attributes are fetched.
* This extension adds that offset in the form of a {@code baseinstance} parameter to several new procedures.
*
* The {@code baseinstance} parameter is added to the index of the array element, after division by the vertex attribute divisor. This allows several sets of
* instanced vertex attribute data to be stored in a single vertex array, and the base offset of that data to be specified for each draw. Further, this
* extension exposes the {@code baseinstance} parameter as the final and previously undefined structure member of the draw-indirect data structure.
*
* Requires {@link GLES30 GLES 3.0}.
