Render this item to a Cairo context.
area | Area to draw, in window coordinates |
Items must convert their own coordinates into window coordinates because Cairo is limited to a fixed point coordinate space that does not extend as far as the Ardour timeline. All rendering must be done using coordinates that do not exceed the (rough) limits of the canvas' window, to avoid odd errors within Cairo as it converts doubles into its fixed point format and then tesselates the results.
Implements ArdourCanvas::Item.
