x/scroll: remove scroll example

opengl: release current context after use

For this example it doesn't matter, but for larger programs that may
have multiple contexts, ANGLE seem to behave better when release the
current context before using another.

opengl: use Metal backend on macOS

Metal performs better on resize and display scaling changes, and

opengl: make context current at each draw

macOS uses a single thread for all window event loops, which means
the window context must be made current at each draw. The "opengl"
example doesn't create multiple windows, but programs based on it
may.

opengl: add example that demonstrates OpenGL rendering to a Gio Window

This example builds upon recent work in the core Gio library that
enables mixing custom rendering with a Gio UI. Unlike the glfw example,
this example uses a regular Gio app.Window configured to not create a
GPU context.
