Drop cairo-vg surface
OpenVG is a failed experiment from 10 years ago, and nobody has been

Remove BeOS support

- * - Correct repeat mode; right now, every surface source is EXTEND_REPEAT
- * - implement EXTEND_NONE (?? probably need to clip to the extents of the source)
- * - implement EXTEND_REFLECT (create temporary and copy 4x, then EXTEND_REPEAT that)
- *
- * - stroke-image failure
- *
- * - Implement mask() with non-solid masks (probably will need to use a temporary and use IN)
- *
- * - Implement gradient sources
- *
- * - Make create_similar smarter -- create QPixmaps in more circumstances

- * - Implement show_glyphs() in terms of Qt
