(Menu Widgets) Add scaling

[jdgleaver]

Description

This PR adds automatic scaling of menu widgets

• For XMB, the scaling is resolution based (since that's how XMB itself is scaled)

• For all other menu drivers, the scaling is DPI based

Scaling is adjusted via the regular Menu Scale Factor setting under User Interface > Appearance (for RGUI, this setting is called Menu Widget Scale Factor, since RGUI does not scale as other drivers do!).

NOTE: Dynamic scaling of queued message widgets doesn't really work, since this is hard and very annoying to deal with - and moreover, any existing queued messages generally disappear rapidly enough that small glitches are not an issue. Permanent notifiers do scale in real-time, though, and of course: any newly pushed messages will use the current scale factor.

Maybe don't duplicate this in both menu widgets and ozone?

After some testing, I think an override setting might be necessary.

Here's how it could work - it would look like the 'Menu Scale Factor', except instead of showing '1.00x' by default it would show 'Off'. 'Off' would mean that it scales with the menu scale factor.

The possible values other than 'Off' would be a a dropdown list that has the same possibilities as Menu Scale Factor. If set to any other value other than the default 'Off', it would apply this override for widgets.

Of course, the value 'Off' is only for presentation - if you're going to implement this as a float value, you can come up with some other value, as long as the representation later on shows it as 'off' in the menu.

You'd place this setting in Onscreen Display -> Onscreen Notifications

Okay, just pushed a substantial update with many internal changes...

• Widget scale can now be set independently of menu scale via two new options under Onscreen Display > Onscreen Notifications: Auto Scale Menu Widgets (uses menu scale when enabled) and Menu Widget Scale Override (used when Auto Scale Menu Widgets is false)

• Ozone scale capping is now internal to menu_driver's menu_display_get_pixel_scale() and menu_display_get_dpi_scale() functions - i.e. all special handling is in one place, so we can use scaling everywhere (menu, widgets, input pointer handling) without any special considerations.

• Ozone smooth ticker text animations now use DPI scaling (instead of a hard-coded multiplier)

• Bug fix: Widget FPS text can no longer be clipped off the left hand edge of the screen

I had to change a lot of established code to make this work - testing would be appreciated...

The new widgets are great, but I have a problem with scaling when using on my CRT screen via a RGB-pi.
The Widgets appear squashed and unreadable. I suspect this is because I'm using "super resolution" on my CRT as I suspect many do - for me 1536x240.

If there a possibility to please correct for this by adding a horizontal scaling factor? or another setting I should be looking at ?

FYI - My menu initially also appeared squashed (though the game was fine) I was able to correct this within Settings -> User Interface -> Appearance - "Lock Aspect Ratio" to OFF
rgui_aspect_ratio_lock = "0" in retroarch.cfg

I use 2560 super resolutions and of course the widgets/notifications appear even more compressed.
Horizontal scaling or similar solution would be very much welcome 👍

Thirding here as an user of 2560x240 Super-Res from my RA to 21" Trinitron-CRT via Ultimate Scart Adapter to mini-Displayport VGA adapter. Being able to adjust horizontal and vertical positions of graphical widgets on top of scaling would be very welcome.

No fix for this yet, can't seem to find a way to scale the notifications horizontally. CRTswitchres 2560 Super Res

[mistikkmodels]

Any FIX for compressed notifications with superres¿??

[MessiahMozgus]

wow, this was never fixed? I'm on Pi3 with VGA to YPBPR, super res 240p setup. The widgets look awful like above.
