A bit more on edit control margins

[Duane Clark]

I went ahead and took a bunch more measurements of font margins in the 
edit control. These are all taken on real Win2k using traces added to 
the conformance test test_margins_font_change, and cross compiled with 
MinGW. So here they are for posterity.

The results are rather confusing to me. But there seems to be a general 
trend.
If MinA < MinC, then the trend seems to be something close to:
   left  = (- MinA - MinC) / 2
   right = (- MinA - MinC) / 2

if MinA >= MinC
   left  = (- MinA) / 2
   right = (- MinC) / 2
