/*
* Objective(s):
* 1. Want triangles with a specified area (e.g., 8sq pixels) for the
* purpose of generating a graphics load with reasonably precise
* characteristics .
* 2. Want triangles to *all* remain on-screen so that triangle rate
* reflects the cost of rendering visible triangles/fragments.
*
* Approach:
* 1. build a base mesh of vertices. This set of verts is positioned
* so that it will remain entirely within the view frustum no matter
* how we rotate it (in 2D)
* 2. dispatch off the mesh vertices as disjoint triangles using
* vertex arrays. This approach is not the most efficient way to
* represent densely packed triangles, but has a couple of benefits:
* - It allows us to easily set the maximum number of triangles per
* frame to be dispatched off to the renderer w/o having to resort
* to tricks like inserting degenerate triangles in strips to connect
* up two disjoint strips.
* - It allows us to glDrawArrays rather than glDrawElements. The latter
* uses one level of indirection, and will be less efficient.
* - In the end, we care about vertex rate, not triangle rate.
*
* An early version of this code used the glDrawElements with indices.
* Rather than insert compile-time switches, this old code is simply
* cut-n-pasted and commented out at the end of this file.
