wasm: Document and test OpenGLContext limitations There is a limit in WebGL that OpenGL context sharing is not supported. There is a proposal from 2013 (https://www.khronos.org/webgl/wiki/SharedResouces), but it seems that it never was implemented. There is an additional limit in that there is exactly one WebGL context for each canvas (i.e. window). A part of the problem here is that the identifier for an OpenGL context is essentially a surface-thread-context triplet. And the thread part might be more difficult to handle in a javascript setting. Regardless of why, we need to have an opinion about what the consequences are, and what we support to what extent. As such this commit: 1) Adds a comment on the QOpenGLContext describing the limitations 2) Adds a qWarning() on the first activation of a shared context. The second item is not complete. We will have problems with multiple individual contexts also, It is just not possible to warn for these cases. The second item covers, maybe, the most common case.
