b04e6c00b0 Introduce a global volume variable 2015-11-14 13:04:16 +01:00

570aa33a20 added test for vibrato... and fixed vibrato 
naturally when i actually tested it, it turned out to be subtly broken

also reorg'd the tests a bit, sorry @hillerstorm.

8c37c8d96b Separate html "shell" javascript; player now standalone 
Closes #3.

The code which defines what the buttons do and downloads songs and so
forth are now completely separated from the player, which has the
following API:

 - `XMPlayer.initAudio` -> starts up audio context; it's available as
   `XMPlayer.audioctx`
 - `XMPlayer.loadXM(ArrayBuffer)` -> returns `true` if loaded, otherwise
   barfs randomly
 - `XMPlayer.playXM()` -> starts playing
 - `XMPlayer.pauseXM()` -> obvious
 - `XMPlayer.stopXM()` -> obvious; call this before loading a new one

Loading trackview.js is now optional; without it, the player won't do
any visualizations. Or, you can override the following to get callbacks:

 - `XMView.pushEvent(e)` -> push an audio event onto the queue. Called
   once per tick (about 50Hz, controlled by song). `e` contains fields:
   - `t` - audio timestamp
   - `vu` - Float32Array of RMS power (volume) for each channel
   - `scopes` - [Float32Array] of oscilloscope data, one array per
     channel; `XMView.scope_width` contains # of samples to produce here
   - `songpos` - position in the song (# patterns played)
   - `pat` - pattern number currently playing
   - `row` - row within pattern
 - `XMView.pause()` - pause visualization
 - `XMView.stop()` - stop/reset visualization

8e114a16da Split viewer code into trackview.js 
Also disabled iOS hack, as it seems to be causing issues, and fixed a
minor drag-n-drop bug (wouldn't load if track was already playing past
length of newly loaded track).

To play without a viewer, you still have to stub it out. Not sure the
best way to handle that case yet.

Many, many fixes found after posting this on my website.

 - drag n drop supported
 - plays on OSX and iOS safari now
 - random other hiccups fixed

there seems to be some remaining issues cleaning up when loading a new
song.

awesome. you can really see the filter effect too.

acffa056a5 *really* fix instrument triggers 
last commit was completely wrong. also i read somewhere that the
instrument alone doesn't reset volume, which is apparently a lie.
