ui/gtk: Add scale option
Allow user to set a preferred scale (defaulting to 1) of the virtual
display. Along with zoom-to-fix=false, this would be helpful for users
running QEMU on hi-dpi host desktop to achieve pixel to pixel display --
e.g., if the scale factor of a user's host desktop is set to 200%, then
they can set a 0.5 scale for the virtual display to avoid magnification
that might cause blurriness.

ui/spice: Blit the scanout texture if its memory layout is not linear
In cases where the scanout buffer is provided as a texture (e.g. Virgl)
we need to check to see if it has a linear memory layout or not. If
it doesn't have a linear layout, then blitting it onto the texture
associated with the display surface (which already has a linear layout)
seems to ensure that there is no corruption seen regardless of which
encoder or decoder is used.

ui/spice: Create a new texture with linear layout when gl=on is specified
Since most encoders/decoders (invoked by Spice) may not work properly
with tiled memory associated with a texture, we need to create another
texture that has linear memory layout and use that instead.
Note that, there does not seem to be a direct way to indicate to the
GL implementation that a texture's backing memory needs to be linear.
Instead, we have to do it in a roundabout way where we need to first
create a tiled texture and import that as a memory object to create
a new texture that has a linear memory layout.

ui/console-gl: Add a helper to create a texture with linear memory layout
There are cases where we do not want the memory layout of a texture to
be tiled as the component processing the texture would not know how to
de-tile either via software or hardware. Therefore, ensuring that the
memory backing the texture has a linear layout is absolutely necessary
in these situations.

ui/spice: Add an option to submit gl_draw requests at fixed rate
In the specific case where the display layer (virtio-gpu) is using
dmabuf, and if remote clients are enabled (-spice gl=on,port=xxxx),
it makes sense to limit the maximum (streaming) rate (refresh rate)
to a fixed value using the GUI refresh timer. Otherwise, the updates
or gl_draw requests would be sent as soon as the Guest submits a new
frame which is not optimal as it would lead to increased network
traffic and wastage of GPU cycles if the frames get dropped.

ui/console: Remove dpy_cursor_define_supported()
Remove dpy_cursor_define_supported() as it brings no benefit today and
it has a few inherent problems.
All graphical displays except egl-headless support cursor composition
without DMA-BUF, and egl-headless is meant to be used in conjunction
with another graphical display, so dpy_cursor_define_supported()
always returns true and meaningless.
Even if we add a new display without cursor composition in the future,
dpy_cursor_define_supported() will be problematic as a cursor display
fix for it because some display devices like virtio-gpu cannot tell the
lack of cursor composition capability to the guest and are unable to
utilize the value the function returns. Therefore, all non-headless
graphical displays must actually implement cursor composition for
correct cursor display.
Another problem with dpy_cursor_define_supported() is that it returns
true even if only some of the display listeners support cursor
composition, which is wrong unless all display listeners that lack
cursor composition is headless.
