* In GL 4.5 core spec (Feb2/2015 version), we have:
*
* >>
* The index of any element transferred to the GL by DrawElementsOneInstance
* is referred to as its vertex ID, and may be read by a vertex shader as
* gl_VertexID. The vertex ID of the ith element transferred is the sum of
* basevertex and the value stored in the currently bound element array buffer at
* offset indices +i.
* <<
*
* So for glDrawElements*() derivatives, we will be expecting gl_VertexID to be set to
* (basevertex + index[i] + i)
*
* DrawArrays does not support the "base vertex" concept at all:
*
* >>
* The index of any element transferred to the GL by DrawArraysOneInstance
* is referred to as its vertex ID, and may be read by a vertex shader as gl_VertexID.
* The vertex ID of the ith element transferred is first + i.
* <<
*
* For regular draw calls, gl_VertexID should be of form:
*
* (first + i)
*
* In both cases, gl_InstanceID does NOT include the baseinstance value, as per:
*
* >>
* If an enabled vertex attribute array is instanced (it has a non-zero divisor as
* specified by VertexAttribDivisor), the element index that is transferred to the GL,
* for all vertices, is given by
*
* floor(instance / divisor) + baseinstance
*
* The value of instance may be read by a vertex shader as gl_InstanceID, as
* described in section 11.1.3.9
