Cockpit scales both ways and re-fits on resize, aspect locked

The canvas was capped at 100%, so a bigger monitor got a 1920x1080
cockpit in the corner of the screen and maximising did nothing - the
layout only ran once at startup.

Now the fit is one uniform scale with no ceiling, recomputed whenever
the window changes size (maximise, restore, drag), and the canvas is
centred in whatever client area it gets. Uniform scale is what locks
the aspect: a wider-than-16:9 desktop letterboxes with even black bars
instead of stretching the cockpit. Panes gained Resize() so the glass
and its button banks re-scale with the canvas; the pixel buffers keep
their native source resolution.

Scaling up is free quality on the MFDs - their glass is a downscale of
a native 640x480 channel until about 200%.

Verified on the 3440x1392 ultrawide: opens at 125% (2400x1350) instead
of 100%, maximises to 126% centred with even bars, a 1884x661 window
fits 61% letterboxed left/right, 1084x961 fits 56% letterboxed top/
bottom, and a 2584x1461 client scales up to 134%.

The 3D still renders at -res and D3D stretches it to the canvas, so
raise -res to match a large screen for 1:1 pixels; start-windowed.bat
and the README say so.
