randr: inherit XError in error classes

fransklaver · fransklaver · commit 52800b1925c0 · 2022-12-25T22:24:06.000+01:00
Commit c87624d ('Add Randr error classes and register them during init') introduces three new error classes to xrandr, but makes them inherit from Exception. Let all error classes in randr inherit from Xerror, like all other code expects. Fixes the traceback ``` ...
