These should effectively be the same, thought the one we've calculated
may be clipped with the scissor. The end result of the math should be

Currently we're passing in a surface, a buffer, and an output. All of
these things are available in the paint node.
Further, if we pass in the paint node directly, we don't have to walk

upcoming repaint.

There are no longer users of these two function. With the
weston_view_move_to_layer() helper being capable of doing this it is time
to retire these entirely to avoid users using them.

When multiple outputs are present, a failure in one's repaint will
cause any repaints of all other outputs to be cancelled. If this
happens during the headless "frame" time, the assertion on
repaint_status in weston_output_finish_frame fails.
Do the same as the DRM backend does in its equivalent callback
drm_output_update_complete and don't finish the frame.

This makes the toytoolkit event loop more robust. Now it uses the
canonical wl_display_prepare_read(), read() and cancel().
Also, it allows functions that run before the event loop to create
Wayland queues and dispatch events related to such queue. Before our
changes, this would cause issues, because of how the loop was written
and also because dispatch_queue() reads the display fd and queue them on
the appropriate event queues, it doesn't read only the events related to
the queue we are interested.

A paint node with 'n' rects damaged by 'm' quads emits 'n*m' OpenGL
draw calls. This commit batches the 'n*m' clipped polygons into an
indexed triangle strip damage mesh using degenerate triangles. A
single draw call per paint node is emitted to reduce API overhead.
Fan debug mode is disabled for now and will be added back using
batching in the next commits.

The repaint loop is started when a client provides a new frame while the
compositor is idle. This frame should be shown as soon as possible. So it makes
no sense to commit the previous frame one more time before rendering the next
frame.
Just call weston_output_finish_frame() directly to start repainting immediately.
As a side effect, this fixes an issue when the output is resized when no
fullscreen shell is involved: At that point, parent.draw_initial_frame is
already false, so draw_initial_frame() is not called. But when resizing, the old
buffers are removed so the commit happens without a buffer attached to the
surface. So the surface is invisible for one frame until the next one is
rendered.
draw_initial_frame() is not removed here, because it is still needed for the
synchronous resize that happens with the fullscreen shell.

When resizing the terminal, the row/columns would end up potentially too tall
and/or wide, meaning the widget would grow each time the window was configured
with a size.
Fix this by making sure the calculated rows and columns don't loose too much
precision, and if they do, shrink instead of grow, as that is expected by the
xdg_toplevel configure event.

Assume axis alignment using node's valid_transform boolean instead of
relying on the transform flags of the weston_view struct. This is more
reliable since matrix flags could erroneously hang around after a
series of transforms. Additionally, nodes with standard output
transforms like translations, flips and rotations by 90° can now take
the fast axis aligned path.

When we lift planes entirely out of the scene graph, paint node visibility
calculations become "per plane". This means that when we lift something
onto a paint node, anything beneath it will be redrawn in response to
client side damage even if the lower surfaces are occluded.
Instead, keep the scene graph together and make the paint node visible
regions be their visibility within the global scene graph.
This has the side effect of plane motion causing redraws, to update
regions they've been obscuring. My assumption is that moving planes
is less frequent than damage being posted beneath an overlay, and
that we'll be more efficient for normal use cases this way.
An optimization is in place to prevent redraws when moving transparent
planes, as they haven't been occluding updates.
In addition to theoretically removing some wasteful rendering time, this
also simplifies damage accumulation.
