test if the object a webgl context
MIT License
Test whether the given object is a WebGL or WebGL2 context. This is useful to handle edge-cases, such as when Chrome WebGL Inspector wraps WebGLRenderingContext in a different type.
Runs in Node and the browser.
var isGL = require('is-webgl-context')
isGL(foo)
isGLContext(obj)
Returns true if the object is an instance of WebGL[2]RenderingContext, handling edge cases for WebGL debuggers/inspectors.
