Re: [Public WebGL] Adding internalformat param to all texImage2d variants

So if I understand this correctly the suggestion is a 1 channel PNG will be auto converted to a 1 channel texture GL_ALPHA or GL_LUMINANCE. a 2 channel will become GL_LUMINANCE_ALPHA. a 3 channel image to a GL_RGB and a 4 channel image to GL_RGBA

So are you adding the requirement that all browsers that support WebGL track this info when loading an img? Or will some browsers that happen convert a 1 channel png to RGB on loading be okay with generating an GL_RGB textures since that's what they have in memory? 

It seems like this auto-conversion step is having WebGL extend itself outside of WebGL into the browser spec.

How about dropping the auto-conversion suggestion and just keeping the explicit conversions?
