Change the style of line that is already drawn?

Hi guys

It's been a long time since working with Pixi.js. Since the version 1.6 is 'in da house' with the ability to fill up complex polygons, I resumed my project again.

As the title says, I draw thousands of lines on WebGL using Pixi.js Graphics class. Then I change the style of the lines.

For example, say I drew 1000 lines on the screen, then I want to update their styles (width, color and etc) somehow not by drawing them again.

Is there a way to achieve this? (possibly for polygons as well?)
