ExportRun measures Java's print panel (GUIContainer.prepareExportPanel) and
image on four projects and an empty one: 10 to spare around, a light grey
footer 20 below the lowest element, 20 below it, a transparent background,
the documentation painted as in the design. The sidebar gains Java's
"Exportieren": the surface painted with Canvas 2D (an SVG with a
foreignObject taints the canvas in WebKit) and saved under the project's
name; Java's message when saving fails. Not adopted: Java's empty image of
an empty project (its footer overflows). The editor takes a projectName;
the capture export shares the download helper.
