Possibility to embed game info icons within gamegrid tiles. (theme dev)

[pajarorrojo]

Issue description

It would be fantastic to have the ability to use game info icons such as wheel (steering wheel), lightgun, manual, savestate, etc., in the same way we use grid.favorite, grid.marquee, grid.cheevos.. etc. Additionally, these icons would only be displayed if the "SHOW X ICON" option is enabled in the user interface settings.

Thanks!

In this regard, the icons of the options in the screenshot called with the extra binding variables {game:x} (savestate, manual, cheevos, gun and wheel) should be hidden or deactivated by default when those options are unchecked. It's a bit confusing to have icons related to this that don't respond to the main configuration. Those options only work in the detailed view for the icons that appear next to the name in the listing AFAIK.

About the "in the same way we use grid.favorite, grid.marquee, grid.cheevos" : my anwser is NO. It would NOT be fantastic at all !
I created itemTemplating to get rid of all those abominable tricks with hardcoded namings ( like grid.favorite, grid.marquee, grid.cheevos ) using hardcoded and non-extensible controls.
I won't make evolve the static hardcoded namings anymore ( all non extras "md_" things, or "grid.favorite" ).

With ItemTemplating, you can do what you want.
See how it's done in content.xml in the carbon theme, it's the perfect sample for what you talk.

Also, you can "read" the options in the theme and toggle display given the option. It's what is done in content.xml.
It works with dynamic and static variables too.

system
showManual                  bool
showSaveStates              bool
showCheevos                 bool
showFlags                   bool
showFavorites               bool
showParentFolder            bool
showGun                     bool
showWheel                   bool

See the documentation here
https://github.com/batocera-linux/batocera-emulationstation/blob/master/THEMES_BINDINGS.md

You can access these options anytime.
There won't be any automatic way to hide what's created with extras ( as it's impossible ).

So, it's now the theme developers responsability to show or hide those elements, given the options.

Okay sir, I had no idea that the showX variables 'read' the options of the UI they refer to. I will do it that way, of course! It might be a good idea to clarify this in the documentation about bindings with a comment next to it ;)

I will investigate how to display the icon within the grid using the new coding
