| concurrent draw operations on that <a href="XBitmapCanvas.html">XBitmapCanvas</a> |
| interface and modifying operations on this bitmap interface |
| might cause undesired effects. Although the implementations |
| are required to not crash in this case, the result of such |
| concurrent operations are <em>undefined </em>(i.e. anything |
| else, including corruption of the bitmap data, or deadlocking, |
| might actually happen). Thus, it is highly recommended to |
| externally serialize the access here. <p> |
