Full screen fills the window's own panel (the margin drops to zero).
Meta+scroll over a floating window changes its scale at the same size in
pixels. Spare outputs are sized to a multiple of KWin's buffer scale, and
screens to even sizes: an odd buffer at a fractional scale is a protocol
error that disconnected KWin. The 3D mouse's drag lock now crosses onto
other Frametop panels unless the pressed one is being carried.

ft-screens makes a panel for each spare output (frametop.float.N), hidden
until ft-floatd floats a window on it. The panel shows only the window's
rectangle of the buffer at the density of the screen it came from, its
popups and dialogs get small panels over it, pressing its title bar
carries it while KWin's pointer stays put, the corner tab resizes the
window in pixels, and two more buttons close it and put it back on the
desktop. The session adds FLOAT_SLOTS spare outputs to KWin and starts
ft-floatd; ft-layout arranges only the screens' outputs, and the pointer
helper treats the new panels like screens. Not yet tried in the headset.

ft-floatd loads the script into the desktop's KWin, which reports windows
over D-Bus and takes commands through a long poll. Floating a window (the
window menu's Float in VR, Meta+Shift+F, or ft-float) turns on a spare
output sized to the window plus a margin, moves the window onto it, and
tells ft-screens the panel's crop, density, and place; docking puts it
back and turns the spare off. Tested on the headless test desktop; the
panel side in ft-screens comes next.

ft-screens --no-vr runs without SteamVR and leaves the input relay alone;
--control names its control socket; "toplevels" lists KWin's windows with
their titles and sizes; "input" feeds pointer events as if from a panel.
screens/test/headless.sh starts it with a bare nested KWin next to the
running desktop, and loads KWin scripts, runs apps, and takes screenshots.
