Int vs float rectangles with scaling: a proposal for Windows/MacOS consistency for JUCE 8

[chkn]

I think it boils down to the inconsistent behaviour of fillRect(int, int, int, int) on the windows software renderer.

Subtle drawing bug(?) -> fillRect (integer version) scaled

Hi Andreas, its totally normal that with a non integer scaling factor, that calculated pixel positions may will collapse on the same physical position. Example: if the non-scaled coordinates are 2 and 3, they will transformed to 2,5 and 3,75 (with scaling 1,25) and will be part-wise mixed on the same physical pixel 3. The problem described in this topic is that there is a graphic function doesn’t work this way: the int version of fillRect. If you use this function, you should replace it with…

        g.fillRect (10, 2, 2, 2);
        g.fillRect (20.f, 2.f, 2.f, 2.f);
