Yes, this looks rather small.

Could you please move the logging code one level down into the NSButtonCell and 
report from there how this is calculated? Also report the image size as seen by 
the cell. You could check the value of s.height at the end of the method and if 
it is huge report textSize, imageSize and border

An image position of 2 should be NSImageLeft, which is fine.

Cheers,
