Log:
#591: Rework PlotAsPDF.php
- Draw the print elements (title, scalebar, disclaimer) first before drawing the map/legend. These draw methods now return a Metrics object containing their position and size.
- Use these returned metrics to calculate the ideal size for the map and/or legend image that we want to put into the PDF. The end result is that the map and legend will better fit inside the PDF regardless of the size of the title or disclaimer as the map/legend will be re-adjusted in such cases.
