Webgl 2.0

[MasonJohnHawver42]

Will Raylib ever use Webgl 2.0? is there a plan to use it? is there a reason why we still are using Webgl 1.0?

[raysan5]

raylib only supports OpenGL ES 2.0 that maps to WebGL 1.0, that is probably more than enough for most raylib users. What would be the benefits of supporting WebGL 2.0 vs the cost of implementing it?

Where can I start implementing it?
Edit: The same solution can be used that supports Opengl 4.3 because Webgl 2 is backwards compatible, right?

Just added some flags to support OpenGL ES 3.0 context creation (despite limited to OpenGL ES 2.0 functionality for now). It has not been tested, feel free to report any issue: e497603

You deserve a truckload of gratitude. :)

I did indeed test all this and have made some good progress. Got my code running on WebGL2 + ES 300 + floating-point textures + Multiple-Render-Targets. I had to complete some stuff related to the initialization flags, though. I will follow up on e497603 shortly.

@chemaguerra Good to know that it somewhat worked, feel free to send a PR if some part require to be reviewed. Additional functionality could be exposed just using the #if defined(GRAPHICS_API_OPENGL_ES3).

I finally gathered some time to clean-up and test my changes properly. I sent a PR: #3107
