►Small but important improvement: lowered the bubble size where the lower resolution bubble images are used in contact widgets
►See the attached (magnified) screenshot for the effect (left: before, right: after)
Smaller bubbles have always used a lower resolution image for better use of system resources. The faces are also slightly magnified for easier identification in tiny sizes. This change affects the bubble size at which the higher quality images start to be used.
