On Xfce with compositing off, X11 has no alpha to blend against, so the
transparent background came out as a black box around the cat.
When a window comes up without an alpha channel, TNCat now cuts the window down
to the pixels the drawing covers, using the X11 shape extension, and refreshes
that 15 times a second so it follows the animation. A sitting cat in a 120 x 106
window comes out as 96 rectangles over 29 percent of the window, so most of the
box is gone. Edges are harder than with a compositor, one bit per pixel, and the
log says so and names the Xfce setting that gives smooth ones instead.
The image-to-rectangles step is platform independent and folds every device row
into its window row, which both halves the rectangle count on a scaled display
and keeps a pixel that is opaque in only one of them.
xcb and xcb-shape are picked up through pkg-config on Unix and the build still
works without them. Opaque mode now paints a neutral card rather than the coat
colour.

The CatDefs singleton did not resolve on the reporter's Linux build, which
showed up as "property mood of object CatDefs is not a function". The same
lookup failure made CatDefs.aspect undefined, so the cat window's height became
NaN and the cat rendered as a moving line. The mug survived because its height
used a literal ratio.
The singleton is gone rather than repaired, since nothing in it had to be
shared. The mood name now comes from C++, derived from the enum key, so there
is one source of truth instead of a list in QML that had to match. Window sizes
now follow the implicit size of the drawing they contain, so the proportions
live in the one file that defines them.
Also for X11: TNCat now warns, naming Xfce's compositor setting, when its
window comes up without an alpha channel, which is what a missing compositor
looks like and why the mug had a black background. Opaque mode no longer hides
the chip and the mug. TNCAT_DEBUG=1 logs window geometry.

Every so often a mug appears at the cat's nose, it sits down, dips its head in
and takes a few slow sips while steam rises. M01, optional stop.
The mug lives in its own click-through window like the chip, or inside the
overlay on Wayland. It goes away as soon as the cat is petted, dragged, sent to
sleep or moves on to something else, so no mug is ever left standing.
Also renames OverlayWindow's mode flag, which shadowed QWindow::active.
