In addition, there is no point in these calls. Depth write is enabled by default

Creating a context that shares with a context that is current on another
thread is not safe, some drivers can reject this.

We work this around by astutely introducing an additional context that
lives on the same thread as the scenegraph's context, shares with it, but
is never current. The main thread's WebGL context will then share with
this extra context.

QV4::TypedArray support in Qt 5.5. This allows the implementation now to also
add support for compressed textures and support all getParameter() values.

too since embedded/mobile devices will have it, but let's leave that for later)

Similarly, forcing ES 2.0 for the shared context when the original was ES 3.x is
not necessarily a good idea. So do like desktop GL and request the same version.
