The first OS window on Wayland is created at scale 1 because the
compositor only sends the fractional scale after the surface exists.
The initial size in cells is therefore computed with scale-1 cell
metrics and the window is mapped a few cells too small. The existing
post-map recompute calls glfwSetWindowSize(), but on Wayland that loses
to the compositor's authoritative configure, which re-asserts the size
it recorded at map time. So a window that receives focus (the normal
interactive case) stays too small; a background window that never gets
an activated configure happens to keep the resized value, which is why
it can look fixed.
Correct the size while the window is still unmapped instead. GLFW gains
a hook (glfwWaylandSetInitialWindowSizeCallback) that it invokes when
the fractional scale is applied during creation -- mutter, kwin and niri
send the scale before the first configure -- letting the embedder
recompute the cell-based logical size for the real scale before the
window is mapped. The compositor then records the correct size and its
activation configure agrees, so there is nothing to race.
The existing post-map recompute is kept as a fallback for compositors
that only send the scale after the first configure (sway, Hyprland).
Also add glfwCocoaSetWindowLevel to the glfw.py wrapper generator list:
it was present in the committed glfw-wrapper but missing from the
generator, so regenerating the wrapper (required to add the hook above)
would otherwise drop it and break the macOS build.
Use an explicit runtime check to apply the newer corner styling on macOS 26 while leaving behavior unchanged on older macOS versions for compatibility.
Also add the required QuartzCore framework for linking the corner curve API.
Hide the CSD titlebar subsurface while keeping shadow borders for
resizing. On SSD compositors (GNOME), forces CSD mode to draw
kitty's own shadows without a titlebar.

When showing the window we loop in the wayland backend using a
temporary buffer of blank pixels to force the compositor to finish
setting up the top level surface pronto.
TODO: Set the color of the temmporary buffer to the background color
Avoids a bunch of SIGIWNCH during child startup as not all programs
handle these correctly. Sadly adds about 0.1 seconds of latency to
startup. Will have to look into reducing that. The Wayland protocol is
*so badly* designed.
Follow PEP 0394 and use /usr/bin/env python so that the python in the
users venv is respected. Not that the kitty python files are meant to be
executed standalone anyway, but, whatever.
Fixes#6810
Uses a private API that allows us to control the amount of blurring.
While using a private API is obviously not ideal, it is used by both
iTerm.app and Apple's own Terminal.app, so hopefully it should stick
around. Fixes#6135
