Bug 84312 – [Chromium] Added more params to Chromium-Webkit print api to implement auto fit to page functionality.

• Component: Printing
• Status: RESOLVED FIXED

[kmadhusu]

To fix crbug.com/85132, I need to pass additional print params such as selected printer paper size, printable area and scale to fit value to the plugin print context. Therefore, I modified printBegin() function accordingly. Please review and let me know your comments.

Latest patch uses WebPrintScalingOption.h. This is a new header file. I would like to commit that header file first to support Chrome side changes. Therefore, I uploaded that header file patch in https://bugs.webkit.org/show_bug.cgi?id=84608.

I suspect it would be better to bottle up these parameters into a WebPrintParams
struct.  See for example WebPluginParams.  Exclude the constrainToNode parameter
so that you can reuse WebPrintParams in the WebPlugin printBegin method.

Use WebPrintParams here too.
