WONTFIX due to incompatibility is the correct resolution.

As for "better" it really could be argued in either direction as Owen
suggests above. There are use cases for both scaling and not scaling the
line width.

Billy already volunteered one approach that allows for using transformations
while creating a path without affecting the line width.

Here's another alternative which you might find more suitable for your situation.

Here's a way to set the line width in pixel dimensions just prior to stroking,
regardless of what transformation has been in effect before:

    /* create path here using whatever scaling desired. */

    cairo_save (cr);
    cairo_identity_matrix (cr);
    cairo_set_line_width (cr, width_in_pixels);
    cairo_stroke (cr);
    cairo_restore (cr);

Good luck, and have fun!
