Currently it logs an error if location is none and corner_radius != 0.

But how much of an issue is this? would it make sense to set corner_radius to 0 in this function instead of logging of an error?

I am mostly hitting this issue in WillPower3309/swayfx#456

where I use a bitmask to only enable the corners that are applicable. and repeating (value & mask) != CORNER_LOCATION_NONE ? corner_radius : 0 feels like a bit much
