-/*
-So what are gl_VertexID and gl_InstanceID supposed to do?
-In ES 3.0 and GL 4.1 (Core), this is all we get:
-
-# ES 3.0
-
-> (p78) gl_VertexID holds the integer index i implicitly passed by DrawArrays or
-> one of the other drawing commands defined in section 2.9.3. The value of
-> gl_VertexID is defined if and only if all enabled vertex arrays have non-zero buffer
-> object bindings.
-> gl_InstanceID holds the integer instance number of the current primitive in
-> an instanced draw call (see section 2.9.3).
-
-
-# GL 4.1 (Core)
-
-> (p102) gl_VertexID holds the integer index i implicitly passed by DrawArrays or
-> one of the other drawing commands defined in section 2.8.3.
-> gl_InstanceID holds the integer index of the current primitive in an
-> instanced draw call (see section 2.8.3).
-
-
-# ES 3.1
-
-ES 3.1 retains the wording from ES 3.0, but adds the following clarifications:
-
-gl_VertexID:
-> (p252) 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.
-
-> (p254) 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. If no element array buffer is bound, the vertex ID of the ith element
-> transferred is indices[i] + basevertex. Otherwise, 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.
-
-gl_InstanceID
-> (p255) 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`
-
-
-# Errata
-
-Drivers generally do implement the ES 3.1 behavior.
-A notable exception is Mac's legacy GL (4.1) driver which has two bugs here.
-(Both ANGLE-on-Metal and the system M1+ GL driver seem correct though)
-
-## gl_InstanceID random for DrawArrays calls
-Use ERRATA.IGNORE_GL_INSTANCE_ID to cause these tests to pass.
-
-## Adds `first` to user-attrib instanced fetch ids in DrawArrays calls.
-Use ERRATA.FIRST_ADDS_TO_INSTANCE to cause these tests to pass.
