or permissions are refused later. Release when prim or script are deleted.
Fixes Scene script instance deletion semantics.
Floating text, Rotation, Texture animation, Particle System
This will make "Eye Candy" scripts work without modification in
XEngine. The use of the CHANGED_REGION_RESTART hack is no longer
needed. Implemented in MySQL only, hovertext also in SQLite.
* This is a HUGE OMG update and will definitely have unknown side effects.. so this is really only for the strong hearted at this point. Regular people should let the dust settle.
* This has been tested to work with most basic functions. However.. make sure you back up 'everything' before using this. It's that big!
* Essentially we're back at square 1 in the testing phase.. so lets identify things that broke.
which is a thin wrapper around a IWorkItemResult from the SmartThreadPool.
However, it is very easy to reimplement on top of basic threading and therefore
makes the IScriptInstance class independent of the specific threading
implementation.
engines that want to use the XEngine's instance handling and state
persistence can do so. IScriptInstance is optional, but it does
require the SmartThreadPool if it is used.
