Rounded corners in dp and in wrong category

[mrgreywater]

The rounded corners setting is in the headphones category:

treble_app/app/src/main/res/xml/pref_misc.xml

Line 64 in 5dbc37b

android:title="Set rounded corners diameter"

Also it seems to be in dp instead of physical px, therefore it needs to be adjusted depending on the dpi in the android settings.

If the settings where taken from the user as px, they could be converted to dp with something like

int dp = (int) Math.ceil(getResources().getDisplayMetrics().density * px);
