The problem we face there is that Windows TextOut() is used to paint the text and that function does not support such formatting.
Yesterday I thought about painting twice, first in bold then again in no bold, but the bold parts should be turned into spaces
and that will not properly fit in the exact place.
Thats why I finally realized that we can use another bold item placed on top of the text we want to be bold.
Not sure if the final result will be fine. But I think it could be a valid solution.
