reduce paramters of texElementImage2D

[cabanier]

The API is currently defined as:

undefined texElementImage2D(GLenum target, GLint level, GLint internalformat, GLenum format, GLenum type,
                              Element element);

Is level necessary?
Will there be support for rendering to other spaces than 8 bit RGBA? (RGB/RGB16F/RGBA16F/RGB32F/RGBA32F) Maybe we need to simplify it and only support RGBA for now and add support for other spaces later.

@kenrussell, do you think this repo is a good place to discuss this, or should it be in the WebGL one?

[kenrussell]

I think the WebGL repository at https://github.com/KhronosGroup/WebGL is the best place to discuss this entry point because there are nuances specific to the WebGL API that are best archived there.

ok. that sounds good.
How can we make sure that the people that work in this repo are aware of that conversation?

For example we can directly reference KhronosGroup/WebGL#3751 .
