* enable anti-aliasing
* increase teapot resolution
* rework teapot display list offset to 0 for convenience
* add font for frame-budget and debug text
* add on-screen ascii text to cache test to get a feel for fonts
* reduce cache test resolution to VI-padded 576x432
* rework other rendering settings (maybe no real difference)
* tweak task pushing (maybe no real difference)
sadly this breaks compatibility with high-level emulators
such as project and mupen, but that ought to be easier to fix
than this damned bug that escaped me for literally a month.
