<pre>Cairo 1.10 prints lines with alpha just fine. Switching to a Cairo 1.12.10 DLL,
all my alpha lines turned opaque and print solid black.
When printing with 1.12.10 in Linux, my lines are still printing with alpha set
correctly.
Example code:
cairo_save( cr );
cairo_set_source_rgba( cr, 0.0, 0.0, 0.0, 0.25 );
cairo_set_line_width( cr, 8.0 );
cairo_move_to( cr, cwidth / 2 - ( 100 - x ), ( y ) / 2 );
cairo_line_to( cr, ( cwidth / 2 - ( 100 - x ) ) + length, y / 2 );
cairo_stroke( cr );
cairo_restore( cr );</pre>
</div>
