[SCR-399] Texture animation by specifying arbitrary frame sequence

[Fenix Eldritch]

Hi folks!

While working on a project, I discovered the need for more control over texture animating (without having to resort to repeated llSetLinkPrimitiveParamsFast() calls. I drafted up a JIRA request and was hoping to get some feedback on it.

The gist of it is a new function which looks nearly identical to llSetLinkedTextureAnim() but replaces the start and length parameters with a list. That list would contain integers (indexs of the animation frames).

After digesting it for a day, one concern comes to mind, would the overhead of sending a potentially large list to the viewer to store and locally animate be more costly than repeated set prim params?
