Bug Description
The latest Cairo 1.9.x releases (which are now in Ubuntu Maverick) use caching for image surfaces, resulting in direct pixel operations in Pinta not drawing correctly.
Therefore, all operations modifying pixels via pointers must be surrounded with Flush/MarkDirty, like this:
surf.Flush ();
// Modify some pixels on surf directly
surf.MarkDirty ();
