Printing Support

[cwensley]

Should add mechanisms to support printing. Should support print dialog, and specify what to print either through a graphics context or a window of controls.

Need to ensure WebView supports printing as well through javascript.

[lubos]

this would be great

WebView printing through javascript on Mac is underlying issue affecting all Objective-C developers so I don't think this can be easily fixed but simply adding Print() method on Eto.WebView control would help a lot.

[cwensley]

printing through javascript might be able to be handled by triggering an event on the webview, which then you can perform your own logic, such as calling print on the web control. The tricky part might be trapping that event, if it is not easily done.

Finished printing infrastructure on all platforms with commit a5b9c44

Some future things to consider, depending on need:

• Printing of controls (this might not be doable in gtk?)
• More PrintSettings options like page set (odd/even pages), and duplexing
