WebGL related part GraphicsDevice is moving to a separate class

[mvaligursky]

Related to #3986

A base GraphicsDevice class is going to be platform independent, and WeblGraphicsDevice will contain WebGL specific implementation. In this first step, the whole implementation was simply moved to WeblGraphicsDevice.

Have you tried using git mv graphics-device.js webgl/blah ? Might keep better history this way.

I did, git mv and few different ways. Some of them work if you only move / rename file. But as soon as you modify it, the operation changes to delete/create pair. The suggestion online is to move / rename in a separate PR to the modify. But we cannot move files without modifying .. at least import paths.
I even created a test PR with two commits, first to move, second to change ..
#4007
when you inspect commits, there's perfect, the one with changes only shows small changes. But when you look at changed files for whole PR, the story is different :(

I'm also trying to split it into two separate PRs .. maybe that's a better way. Here: #4009
I moved graphics-device.js to webgl subfolder .. and it's seen as move, even when I fixed the import paths. So this might preserve the history better. So maybe I do this as a first step, and then do follow up refactor after #4009 is merged.

closing this one, as this has been done using two steps in order to preserve git history of GraphicsDevice:

• Move GraphicsDevice to webgl subfolder #4009
• Initial implementation of WebglGraphicsDevice class #4010
