Comment 16 for bug 738973

(attaching a simple test file with 900 paths: the 'Export Bitmap…' dialog opens immediately with both X11 and Quartz backend builds of r10255. The dialog opens quickly due to the low complexity of the objects.
Filter effects, blurs and stroked paths with a huge number of nodes take much longer for the calculation the precise bbox for export. With the test file I mentioned in bug #719993, both quartz and X11 builds of current trunk take > 60 seconds on my system to open the 'Export bitmap…' dialog.)
