Embedded outline graphics!
Finally, the control does what I really wanted it to from the start: It completely encapsulates Highslide JS into a single file. You no longer need a graphics/outlines directory with external outline images. Absolutely everything you need is embedded in the control’s .DLL.
If you’re upgrading from a previous version, drop the GraphicsPath property from your HighslideManager control and feel free to delete the outlines directory from your site.
As always, the latest version is available on the Highslide JS .NET download page.
