Allowing Graphic.validateNow to work as a pre-cacher of StrokeVertices? about starling-extension-graphics

[jonathanrpace]

Hey,

I'm not able to see how or why the stroke class would do its work twice in a frame. The validateNow() function only calls buildGeometry() if 'isInvalid == true'.

How are reproducing this?

[IonSwitz]

The thing I was trying out was to avoid having the geometry generated during the render phase,
and instead be able to call validateNow before rendering starts, such as in a initialization stage.

However, since the "isInvalid" is only set to false in the render phase, this isn't possible.

So, even if I call validateNow in the initialization stage, the geometry will be re-generated during the first call to render(), and that can cause frame-rate hickups.

Maybe I was being unclear about the "being called twice"-reasoning, but I hope this explains the issue better?

Gotcha - seems like a bug to me (it really shouldn't be validating the geometry again if you've already called validateNow()). Will take a look in a few days (out of the country at the moment)

It's a no-brainer, really, to implement. I could throw something together if you prefer.

All it needs is a boolean flag to check if the geometry has been built already.:)

A fix for this has been checked in. Please see separate issue for explanation of what changed.
