Feature: 2x scaling for the native on-screen display

[johnnovak]

The native on-screen display is a great feature and I use it all the time. But it's quite small which is a problem for people with less-than-perfect eyesight, and a potential problem for everyone at higher screen resolutions than 1080p.

Would it be possible to add at least a 2x integer scaling option to the OSD? I've done a mockup, I think it would look nice.

The ideal solution would be to render it with a better font at a size that's somewhere between the current size and the 2x integer scaled size (or make it configurable), but a simple 2x integer scaling would be a nice quick win.

Current at 1080p

Scaling was already possible by undocumented config file entry (show_leds_size and show_leds_size_rtg, parameter is decimal multiplier) but latest beta now has also OSD font type/size selection (misc panel) which hopefully is much more useful.

That's great, trying it today! 🚀

It works splendidly @tonioni, great addition! It even handles very large fonts correctly as shown on the below screenshot, great!

I noticed I can only change the OSD font in "windowed" mode. In "fullscreen" and "full-windowed" modes, changing the OSD font doesn't have any effect. Is this intentional?

[tonioni]

No. Changing OSD font while in full-window or fullscreen mode saved the config incorrectly, making it no-op. Fixed.

Confirming the fix works @tonioni — now I can change the OSD font in full-window and fullscreen mode too. Thanks! 👍🏻

The OSD now works perfectly, but I noticed a small glitch with the floppy insertion message. As you can see, the top of the letters is cut off (view at 100% zoom):

That's with Lucida Console, Regular, size 10.

Ok, let's see how it behaves with a much larger font, let's check out size 16:

Now the floppy message is perfect... but the OSD is misaligned and being clipped. Forcing a refresh/redraw by switching to full-windowed then back to windowed fixes it:

So, two remaining issues:

• Floppy insertion messages are being clipped at the top at certain font sizes (this is unfixable).
• The OSD gets misaligned when changing to larger font sizes at runtime (forcing a full redraw or an emulator restart fixes it).

All visual glitches when changing the font size are fixed in 5.2.0 b7, thanks @tonioni.
