_______________________________________________________
Details:
Cairo drawing in gtk3-client canvas.c is not sensible at all.
- cairo_scale() is used for the final paint operations only, and all the math
before that is in our own code.
- Destination area is clipped and full cairo_paint() is used towards it when
we could use cairo_fill() rectangle
Cleanup to these attached:
- Call cairo_scale() earlier, and let cairo to figure out the math (which was
broken anyway)
- Instead of cairo_clip() + cairo_paint() use cairo_fill().
