Feature request: allow "zooming out"/reducing the scale below 100% if the host display resolution is bigger than can fit on one screen

[sudomain]

If you'd like to put out an incentive for implementing this feature, you can do so at https://issuehunt.io/r/bk138/multivnc?tab=idle

Is your feature request about the Desktop Multivnc or the Mobile MultiVNC?

• Desktop (wxWidgets) or Mobile (Android):android
• If Mobile, installed from Play Store or F-Droid:fdroid

Is your feature request related to a problem? Please describe.

The display of the host doesn't always fit on one screen.
Describe the solution you'd like
The panning feature is nice, but I think a great improvement to UX would be allowing the pinch gesture to zoom out to see the whole display. In other words, zoom in/out is already supported, but zooming out stops when the scale hits 100% (as shown by the android toast that pops up when zooming and says Scale now 100%).

I think it would be great if users could zoom out to a scale of e.g. 90% or 80% by pinching

Describe alternatives you've considered

@sudomain Can you provide more details about screen sizes (remote host + mobile)?

I think we try to reduce minimum scale here. So it may be a bug/edge case.

[sudomain]

From the manufacturer website, my phone has a screen resolution of 1280 x 720 pixels (landscape, 720x1280 portrait?). The "remote" host technically isn't remote at all; it's an instance of TermuxArch running a TigerVNC server on the same device. A lot of technical details of this setup are irrelevant, but I can provide them if needed. What is relevant is that the TigerVNC server creates a virtual display "VNC-0" with resolutions that range between 1920x1200 and 640x480:

Since I mostly want to use MultiVNC in portrait mode (720x1280), I can only use 640x480 to see the whole display.

I'll have a look!

@bk138 what is the expected behavior here? Should the frame - at minimum scale - be entirely visible (in landscape & portrait mode)?
