[x3d-public] TimeSensor Hierarchy

[GPU Group]

Somewhat tangentially related: test automation and MIDI files
- both have sequenced events
- with a delta-time between events
<information about event> dtime
<information about event> dtime
For MIDI the information is the music key aka midiNote:

MIDIOut

{

  MFInt32 [out] octave

  MFInt32 [out] key12

  MFInt32 [out] key88

  MFInt32 [out] keyPiano

  MFInt32 [out] midiNote

}

MidiOctaveOut : X3DUtilityNode

{

  SFInt32 [in,out] octaveFilter -1

  MFInt32 [in] midiNote

  SFBool [out] C

  SFBool [out] Cs

  SFBool [out] D

  SFBool [out] Ds

  SFBool [out] E

  SFBool [out] F

  SFBool [out] Fs

  SFBool [out] G

  SFBool [out] Gs

  SFBool [out] A

  SFBool [out] As

  SFBool [out] B

}

so a midi keyboard could be used to record a midi file, and played back
with the time between notes recorded and affecting when an out event is
triggered.

Test automation: (yet to be published version of) freewrl has --record and
--playback commandline options.

On --record it monitors mouse and keyboard input and writes <information =
mouse xy, button> dtime and <information = key> dtime records in a
<scene_name>.fwplay file. On running with --playback, it reads that file in
a separate thread, sleeping(dtime) between sending the events to the
program.
