Remove volume from being a setting inside core code. Move that setting
into GUI glue code.

Also move globals for GUI into a single object. In addition, keep
copies of all the core settings inside the glue code, and force push
them on page start.

This will simplify web worker code.

For browsers that support typed arrays but not Math.imul.

Stabilize audio buffer initial levels on pause->play change.

Firefox needs more time to schedule its vsync events. It misses a few
even at 16 ms intervals.

Fixes a graphics regression in gunstar super-heroes in the second area
of the intro level.

For some reason we removed the horizontal flip crap for obj-win
recently when rewriting stuff.

cleaning up how we determine some metrics.

Copy old buffer contents into the new buffer if we have to
re-initialize audio. This will allow proper gapless audio playback if
the speed is changed in real time. Well…. except for the "partial
remainder" rollover value used to alter the first output sample of the
next resampling block in the resampled, but that's extremely minor and
not worth complicating the fuck out of the codebase for.

Separate the actual timer into glue code. Also changed some settings
from interval millisecond multipliers to direct millisecond limits.

possible minor optimization as well.

So the most used cases come first. Thankfully we already auto-gen the
switch, so it's a dense gapless switch that has the mappings changed
for us by modifying that list you see.

JITs have changed a little, we can use bitwise ANDs in place of
branches in a bunch of cases now for performance reasons.

Make the BG renderers responsible for handling the raw register data
i/o writes.

This should dumb down the entire renderer code enough for JITs to
follow fully.

There isn’t anymore object passing or function reference overwriting
for polymorphism for graphics rendering.

Re-fix Firefox 3.X support (Yes really, version 3).

Might confuse some dumb JITs and cause additional entry checks.

Convert some branches to bitwise AND’ing a value.

Just expand the layer buffer for include space for a scratch buffer.

converting mosaic storage to uint8

Force the subarray to be int32 inside getInt32ViewCustom.

Fix mosaic status bit width being too small.

Pass priority flag to functions directly instead of caching it.

Just pass the value through the function call.

Have to re-add the xaudiojs submodule.

Just wanted to clear out my account due to account snoopers.
