I have overridden the size handler (_onSize) of FigureCanvasWxAgg. In there I essentially added a few lines to set the DPI value with respect to the current canvas size in order to resize elements as suggested by John (using figure.dpi.set). At a first glance everything works as expected. However, if the canvas becomes too small (and apparently with some font types only) I get the following runtime error: "Could not convert glyph to bitmap". Where is the problem?
