Add dispose functions to release all resources

[hansagames]

Any plans to add dispose for textures , materials, meshes to release resources ?

Hey, yeah I definitely would like to look into this further. Currently I don't have a solid grasp over what needs to be released. Do you know of any good resources?
Cheers

Yes as I created dispose now a bit around framework: :)
1)Textures need to be removed gl.deleteTexture(texture.texture);
2) Texture need to be unbindede:
renderer.gl.bindTexture(renderer.gl.TEXTURE_2D, null);
renderer.gl.bindTexture(renderer.gl.TEXTURE_CUBE_MAP, null);
this is for webgl 1, fro 2 there can be more texture types
3) Geometry and buffer as I saw are already implemented
4) Program remove I saw as well

Also would assume all referenced gl / renderers should be removed as they can get cycle reference, same goes for internal states

To make it working out of box renderers should have references to all textures / programs and meshes if not dispose could be implemented per object only and then user would be responsible to call them.

Technically it is not necessary.
Context will a flushed after losting, for ex - delete canvas or reload a page.
But if you use context a temporary, for ex, animation on SPA, or visualising library - this is maybe a usifull to prevent memory leaks.
