The _NET_WM_STATE protocol description[0] states that to change the
window mode for an X11,
"To change the state of a mapped window, a Client MUST send a
_NET_WM_STATE client message to the root window."
and that the window manager in turn
"The Window Manager MUST keep this property updated to reflect the
current state of the window."
However, our X11 implementation did both: send the message _and_ set or
deleted the property.
This change makes it so only the message is sent. It also replaces
toggling the property by setting or clearing, to ensure our mode and the
window manager's mode never gets out of sync.
Maybe fixes gio#265

Driver methods are invoked during event processing, but some of them may
generate events that would in turn deadlock because event processing is
not re-entrant. However, a previous change moved all such calls outside
event processing and so chained events can no longer deadlock.
This change deletes the workarounds.

Window.driverRun is designed to run functions on the driver event
goroutine, to avoid race conditions with internal driver state and,
more importantly, to run on the designated main or UI thread for
platforms that require that.
However, driverRun runs functions during the processing of a driver
event, so if a function in turn triggers another driver event,
deadlock occurs.
This change introduces Window.driverDefer for functions that don't need
to block event processing. Functions passed to driverDefer may
themselves trigger new events.
A few callers of driverRun remain; they need the result of their
functions but are guaranteed not to trigger new events.

Since onFrameCallback runs on the app UI thread, using plain
invalidate() can be used instead of postInvalidate(). The latter just
schedules a call to invalidate() on the UI thread.
Also, since onFrameCallback is directly called by JNI, there is no need
to set up a new JNI environment to call back into Java.

Some window configurations lead to WM_SIZE messages when changed, which
leads to deadlock because our window proc is not re-entrant. Avoid the
issues by ignoring redundant messages.

The app and app/internal/wm packages are tightly coupled, requiring

There's no meaningful reason to have them separate. The intention was to
enable rendering concurrent with other processing, but that's gaining
framerate at the expense of input latency and complicating ImageOp
semantics.

Both the OpenGL and the Direct3D API are stateful and gpu.GPU renders to
the render target current when Frame is called.
Modern GPU API such as Metal don't have a concept of a current render
target, and the target even changes each frame.
Add RenderTarget and add an explicit target argument to GPU.Frame as
well as the underlying driver.Device.BeginFrame.
