New issue 104 by ni...@amazon.com: dev tool support for webGL debug
https://code.google.com/p/chromedevtools/issues/detail?id=104

SDK/Debugger version: N.A.
Eclipse version: N.A.
Google Chrome/V8 Embedder + version: Any
[For WebKit (WIP) protocol] Backend version: Any
OS + version: Any

What steps will reproduce the problem?
1. Load a webgl webapp in chrome
2. Open Dev Tools
3. Search for ways to inspect shaders

What is the expected result?
Browser debugging support to allow me inspect, trace, snapshot, debug the
gl app. It would provide insights into the shader language, openGL traces,
similar to what we have for javascript/css debugging in devtool. See below
section for more info.

What happens instead?
There is no way for a developer to debug the shader language.

Please provide any additional information below. If possible, attach a
(reduced) test-case.
Related to https://code.google.com/p/chromium/issues/detail?id=367739, but
we want more features:
1.Snapshot of a sequence of frames with gl trace info
2.Allow stepping through shader language
3.Chrome engine trace info similar to the javascript trace feature
available in latest chrome canary dev tool.

Tools available in firefox today:
https://developer.mozilla.org/en-US/docs/Tools/Shader_Editor, and
https://hacks.mozilla.org/2014/03/introducing-the-canvas-debugger-in-firefox-developer-tools/

Tool available in android today:
http://developer.android.com/tools/help/gltracer.html

Today people use
webgl-inspector(http://benvanik.github.io/WebGL-Inspector/) on Chrome to
debug webGL apps. But there is limitations, i.e. it doesn’t support live
edit of the shader languge; it cannot capture a sequence of frames; it
doesn’t show the real openGL calls resulted from the webgl code; it doesn’t
support stepping through the shader language.

Wrong project. This one is about the Chrome DevTools for Java, which is no
longer maintained. Please file a bug against built-in devtools at
http://crbug.com/new.
