Subject: [PATCH] user-chooser: try to find fallback icon more aggressively
|
|
|
|
Some themes won't give you the nearest icon at the requested size,
|
|
so first look up the available sizes and choose the closest
|
|
available one ourselves.
|
|
|
|
If it fails, just fallback to an empty square of the right size.
