ok but from cairo docs:
"
void cairo_paint_with_alpha (cairo_t *cr,
double alpha);
alpha :
alpha value, between 0 (transparent) and 1 (opaque)
"
we now pass a negative integer between -1 and -255 (before this patch we passed
-80), maybe we should do something like this (not tested):
cairo_paint_with_alpha (cr, overlay->shading_value/255.0);
instead of:
cairo_paint_with_alpha (cr, -overlay->shading_value);
