(Core :: Graphics: CanvasWebGL, defect)

Description

[Andor Salga]

User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.3a5pre) Gecko/20100529 Minefield/3.7a5pre
Build Identifier: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.3a5pre) Gecko/20100529 Minefield/3.7a5pre

When a call to getString() is made on the WebGL context, 

alert(gl.getString(gl.VERSION));

Minefield throws and exception:

Error: uncaught exception: [Exception... "Component returned failure code: 0x80004001 (NS_ERROR_NOT_IMPLEMENTED) [nsICanvasRenderingContextWebGL.getString]"  nsresult: "0x80004001 (NS_ERROR_NOT_IMPLEMENTED)"  location: "JS frame :: file:///Users/andor/Documents/processing.js :: size :: line 3995"  data: no]

On Webkit, it returns 
2.0 NVIDIA-1.5.48 for gl.VERSION

Reproducible: Always

Steps to Reproduce:
Call getString() on WebGL context passing in either

gl.VENDOR
gl.RENDERER
gl.VERSION
gl.EXTENSIONS
Actual Results:  
Exception is thrown

Expected Results:  
String should be returned

getString() has been removed from the WebGL spec. Instead, use e.g. gl.getParameter(gl.VERSION).
