BACKENDS: Android - After clean install, graphics settings are not consistent with their state in the GUI

[antoniou79]

After clean install, some options in the Graphics settings like Filter Graphics and Stretch mode have a state that is not correctly reflected in the GUI.

Filter Graphics seems to be enabled, Aspect Ratio Correction is disabled, and Stretch Mode set to "Stretch to Window", *however* the GUI shows Filter Graphics checkbox as unchecked, Aspect Ratio correction as enabled, and Stretch Mode as <default>

To make them consistent via a hacky workaround the user has to check the Filter Graphics, click Apply, then uncheck Filter Graphics and Apply again.

Also the default values for these two options above after a clean install should be:

• Filter Graphics disabled
• Aspect ratio correction enabled
• Stretch Mode Fit to Window

A potentially connected issue is that choosing <default> for the Stretch Mode in the Graphics Tab, does not actually set a default value but keeps the existing setting. This issue (tracked here: https://bugs.scummvm.org/ticket/11744) is not particular to Android.

These bugs could affect other options too (in Graphics or other Option tabs).
