/**
* This is a minimalist program whose sole purpose is to open a .skp or .svg file, benchmark it on a
* single config, and exit. It is intended to be used through skpbench.py rather than invoked
* directly. Limiting the entire process to a single config/skp pair helps to keep the results
* repeatable.
*
* No tiling, looping, or other fanciness is used; it just draws the skp whole into a size-matched
* render target and syncs the GPU after each draw.
*
* Well, maybe a little fanciness, MSKP's can be loaded and played. The animation is played as many
* times as necessary to reach the target sample duration and FPS is reported.
*
* Currently, only GPU configs are supported.
