Resizable virtual display with factor

[rsanjuan87]

feat: allow to resize virual display as the scrcpy window size

left: no resizable virtual display after resize window
rigth: resizable virtual display after resize window

left: --new-display=:r6 ( window size * 6 )
center: --new-display (no reszizable)
right: --new-display=:r (window size * autofactor: calculated from device screen and default initial window size, this case autofactor = 2)

The resizable factor allows you to scale the size to avoid losing image quality.

usage example:

--new-display=1920x1080/420:r2

--new-display=:r

--new-display=/420:r

:rN

r: to indicate resizable screen
N: factor to multiply

tested on: MacOS Tahoe & Redmi Note 11 Pro 5G, & Android Studio Emulator (Android 16)

fixing #6350

This is an actually great commit, and would make it much easier to use on wider displays such as mine!

I don't really understand the meaning of "resolution factor", in particular how it provides additional information not already encoded into width×height/dpi.

EDIT: I understand now, it can be useful to have the virtual display DPI not correlated to the client resolution.

(no resolution) "resizable" factor is to multiply the real window size to send to the virtual display resolution
ex: window size 100x50 with factor 2, will resize the virtual display to 200x100
this will avoid small screen resolution (as same window size)
the width×height/dpi is not applicable as the window will resize the display, you may indicate the initial resolution but after resizing the scrcpy window will resize the display

the autofactor (:r with out N factor) will calculate the factor with default window size and default resolution

Wie kann ich das beweisen? think it's good to have a screen that can adapt to what I need and not just the one that's already created or the actual screen on the device.

Has Chrome switched to desktop mode?

Good addition! The resizable virtual display makes scaling much more flexible while preserving image quality — really improves usability and customization
