As result you can show in a report not only picture from DB, but from disk or by any URL.
Igor have made great job improving speed of reports generation on linux, which uses the FreeType library (instead of wxWidgets+OS like on WIN/MAC). As result, time of report of one developer go down from 3 second to 0.3.
Actually FreeType library can be used on MAC and WIN. Just no big sense because it was much slower.
Now we see sense to enable TWO render-engines on MAC/WIN and be able switch them runtime. This will be useful for building of automated test-system for reports.
