gcc 4.9 has -Wfloat-conversion. I tried it, but it really gives many
warnings (see below) and I am uncomfortable with using it.
I wonder though why MSVC only gives a few of them.
Did you only attached a part of the output ? There are not so

I guess that when you use AntiAliasing, you would be able to actually
draw non-integer widths.
Don't know how Qt handles it though.

OK, this boils down to the change introduced by Uwe at f01e36b6. Uwe,
can you tell us why non integer values are needed? In particular, I do
not know where the 0.5 for line_thin comes from.

Actually, it is a float because we use QPen::setWidthF to set the width

I do not think so, but then I do not know this code well. There are some
additional tricks linked to zoom that cause the value to not exactly be
