[sldev] VWR-10311 Enabling lip sync by default

[Dale Mahalko]

While this is called lip sync, apparently it is really just "jaw-sync".

What happens for the non-human avatars? It doesn't seem to make much sense
for a cyborg to waggle its jaw... if it has one. Maybe have a pulsating-glow
prim on its torso instead. And what about a jellyfish avatar? Might want to
waggle some pairs of flexy flagellum around its umbrella.


This setting doesn't really belong in the client prefs at all. It should be
avatar-specific and so should end up in the avatar Appearance settings for
each avatar to decide for itself whether or not to use, as well as how to
use it or what prims to parameter-animate with it.

Appearance....
[ x ] Enable voice lipsync effect:
( . ) Sync avatar jaw to voice
. . . . Maximum mouth-open scaling: [ 2.000 ]
. . . . [ x ] Sync attachments to jaw
( . ) Sync LSL-enabled prim attachments to voice


In enabled attachment:

default
{
    attach( key id )
    {
        // Enable attachment to receive lipsync scaling
        float MinScale = 0.0;
        float MaxScale = 1.0;
        float Linearity = 1.0;
        llLipSyncPrimParams( llGetKey(), FLEXY_TENSION, MinScale, MaxScale,
Linearity );
    }
}
Constants for setting prim parameters to be lipsynced.

- SIZE_X, SIZE_Y, SIZE_Z, SIZE_ALL
- SCALE_X, SCALE_Y, SCALE_Z, SCALE_ALL
 - COLOR_R, COLOR_B, COLOR_G, COLOR_ALL
 - TRANSPARENCY
 - GLOW
 - TWIST_BEGIN, TWIST_END
- DIMPLE_BEGIN, DIMPLE_END
- CUT_BEGIN, CUT_END
- SKEW
- TEXTURE_SCALE_X, TEXTURE_SCALE_Y
- TEXTURE_ROTATION
- FLEXY_TENSION
- FLEXY_GRAVITY
(etc)

All constants include the MinScale, MaxScale, and Linearity scaling
parameters, and params need to be sane for the particular prim parameter
being animated.

Prim voice-animation modifications would be client-side only and would not
affect prim parameters on the server side.
