Application.renderLine(s) with duration

[Grimeh]

Most of the times I use pc.app.renderLine or pc.app.renderLines for debug purposes I find the lack of a duration option frustrating. I'm rarely in a position where I can call it every frame without recording it somewhere and adding the renderLine call in some script's update, which is not great.

I think both functions would benefit greatly from adding a duration option to the options parameter, where the application would draw the line(s) until the duration had elapsed.

Seems like convenient request, but leads to very specific use case.
Implementing simple array with lines objects and their timers, is 5 minutes task, here you go: https://playcanvas.com/project/664103/overview/renderline-delay

For sure, very easy to add and we have done so for almost every project, to the point where we should probably make it part of our template. But it's such useful functionality for debugging (the primary use case for renderLines I imagine?) that it seems worth the time adding to the interface.

From my experience it seems pretty standard for a "render/draw lines" function to have an optional duration, is there a particular reason for not adding it, apart from extra complexity in scene/immediate.js?
