Dense image rendering

[PPPDUD]

Is your feature request related to a problem? Please describe.
Whenever I click File>Render Image with the Mandelbrot set and enter a large resolution (such as 4K), the rendered image is zoomed out extensively to match the new dimensions. Zooming in yields an increasingly pixelated image.

Describe the solution you'd like
I want to be able to choose a setting where the extra pixels are used for rendering extra inner branches instead, such that zooming in on the picture produces a similar effect to zooming in on the program (more branches become visible).

Describe alternatives you've considered
I've considered saving coordinates in the native XaoS format, but most of my friends don't have a computer to view the file on.

Additional context
Zooming on the program (similar to desired behavior):

zooming.mandelbrot.mp4

Zooming on the picture (bad, overly pixelated):

Thanks for the report! We need to have a deeper look on this, but meanwhile you may want to export the position file as URL in the Edit menu and share the URL with your friends (it will point to the online version at https://xaos.app).

Got it! Thanks for helping me out!
As far as two-dimensional fractal viewers go, your software is very impressive! Kudos to everyone at the Xaos project for the awesome program!
