[sldev] physics simulation

[Dahlia Trimble]

The shape of objects can be determined by collision in many cases, also a
crude representation of shape is available to scripts with the
llGetBoundingBox() API. Sounds are not usually synced well between viewers
and are not available to objects, but if the sound is one that is generated
by an object then that object could also broadcast some kind of message that
another object can "listen" for. Other sounds that are created by collisions
or avatar gestures may not be available to objects at all. Video is a viewer
effect only and is not necessarily in sync between multiple viewers. The
simulator has no information about the video source except for a URL which
it passes to the viewer.
This is all assuming that a robot is built entirely in world. Something more
sophisiticated may be built with a "bot", or an automated avatar client,
using tools such as a modified viewer or libopenmv
