/*
This function does all the stuff needed to translate the game screen,
using the URL given in the settings. Once the image from the frame
buffer is sent to the server, the callback will write the translated
image to the screen.
Supported client/services (thus far)
-VGTranslate client ( www.gitlab.com/spherebeaker/vg_translate )
-Ztranslate client/service ( www.ztranslate.net/docs/service )
To use a client, download the relevant code/release, configure
them, and run them on your local machine, or network. Set the
retroarch configuration to point to your local client (usually
listening on localhost:4404 ) and enable translation service.
If you don't want to run a client, you can also use a service,
which is basically like someone running a client for you. The
downside here is that your retroarch device will have to have
an internet connection, and you may have to sign up for it.
To make your own server, it must listen for a POST request, which
will consist of a JSON body, with the "image" field as a base64
encoded string of a 24bit-BMP/PNG that the will be translated.
The server must output the translated image in the form of a
JSON body, with the "image" field also as a base64 encoded
24bit-BMP, or as an alpha channel png.
"paused" boolean is passed in to indicate if the current call
was made during a paused frame. Due to how the menu widgets work,
if the ai service is called in "auto" mode, then this call will
be made while the menu widgets unpause the core for a frame to update
the on-screen widgets. To tell the ai service what the pause
mode is honestly, we store the runloop_paused variable from before
the handle_translation_cb wipes the widgets, and pass that in here.
