/**
* Post-transform vertex buffering. This is an optional part of the
* softpipe rendering pipeline.
* Probably not desired in general, but useful for testing/debuggin.
* Enabled/Disabled with SP_VBUF env var.
* Interface between 'draw' module's output and the softpipe rasterizer/setup
* code. When the 'draw' module has finished filling a vertex buffer, the
* draw_arrays() functions below will be called. Loop over the vertices and
* call the point/line/tri setup functions.
