Succeeded in showing an image. For now we support only bmp format, but it's easy to support other formats.
What we have done are
- Added setting and changed some. page_->settings()->setLoadsImagesAutomatically(true);
- Called forceLayout()
- Integrated WebView with the native WindowFrame class.
The most difficult point was understanding a relation between
- shared timer loop
- window system loop
- when and how main/sub resource is loaded.
