Fix some issues with lineWidth < 1 after transform (bug 1753075, bug 1743245, bug 1710019) - it aims to fix: - https://bugzilla.mozilla.org/show_bug.cgi?id=1753075; - https://bugzilla.mozilla.org/show_bug.cgi?id=1743245; - https://bugzilla.mozilla.org/show_bug.cgi?id=1710019; - issue #13211; - issue #14521. - previously we were trying to adjust lineWidth to have something correct after the current transform is applied but this approach was not correct because finally the pixel is rescaled with the same factors in both directions. And sometimes those factors must be different (see bug 1753075). - So the idea of this patch is to apply a scale matrix to the current transform just before setting lineWidth and stroking. This scale matrix is computed in order to ensure that after transform, a pixel will have its two thickness greater than 1.
