f0ae8da993 Remove GdkGLContext::visual
This is not really needed. The gl context is totally tied to the
window it is created from by virtue of sharing the context with the
paint context of that window and that context always has the visual
of the window (which we already can get).

Also, all user visible contexts are essentially offscreen contexts, so
a visual doesn't make sense for them. They only use FBOs which have
whatever format that the users sets up.

dbbab0791d GdkGLContext: Track shared context
This allows us to read it back, but primarily it ensures
the shared context wrapper stays alive as long as the context.

fb50015519 GdkGLContext: Change the way we track the current context
To properly support multithreaded use we use a global GPrivate
to track the current context. Since we also don't need to track
the current context on the display we move gdk_display_destroy_gl_context
to GdkGLContext::discard.

0814cd9f8b GdkGlContextWayland: Don't require specific bit depths
This just means we may fail to get a gl context, we just require
*some* color depth.

3013997e23 Rename gdk_gl_context_flush_buffer to gdk_gl_context_end_frame
This makes a lot more sense.

6440263ef3 GL: Follow naming conventions
All the GDK type defines are GDK_TYPE_..., so follow this
pattern for the GLContext subclasses as well.

fdeb4f8c16 gl: Make gdk_gl_context_make_current() return void
Its not really reasonable to handle failures to make_current, it
basically only happens if you pass invalid arguments to it, and
thats not something we trap on similar things on the X drawing side.

If GL is not supported that should be handled by the context creation
failing, and anything going wrong after that is essentially a critical
(or an async X error).

236d08c3c5 gl: Make all user GdkGLContexts not attached to any window
We make user facing gl contexts not attached to a surface if possible,
or attached to dummy surfaces. This means nothing can accidentally
read/write to the toplevel back buffer.
