    Documented at http://msdn.microsoft.com/en-us/library/gg558047%28v=vs.85%29.aspx
  • Table Font Inheritance
    With the exception of font-family, by default table elements do not inherit font properties.

    Documented at http://www.opera.com/docs/specs/doctype/
  • Box-Sizing Model
    Is content-box instead of border-box.
    Described by http://www.quirksmode.org/css/box.html and by Microsoft at http://msdn.microsoft.com/en-us/library/gg558047%28v=vs.85%29.aspx
  • Aligned Images
    Right-aligned images have a default left margin of 3 pixels. Left-aligned images have a default right margin of 3 pixels.
    Described at http://www.cs.tut.fi/~jkorpela/quirks-mode.html and in Mozilla's quirks.css file.

• New Demo FrameBrowserUsingICSv7: Same as FrameBrowserUsingIndy but using Overbyte's ICSv7 instead of Indy (Angus Robertson)

• Issue 130: Non-standard pointer cursor replaced with crHandPoint.
• Issue 150.2: Table column width with '*' even in <td>.
• DoScrollbars runs now at design time, the ugly missplaced scrollbars vanish. (Sérgio Alexandre)
• THtmlViewer now always uses DoGetImage() as event handler for FSectionList.OnGetImage. DoGetImage() now is virtual, thus THtmlViewer descendents can override it and handle images on its own without blocking the OnImageRequest event. (Sérgio Alexandre)
• HandleMeta and InitLoad promoted to virtual, descendents can now do something. For example Sérgio Alexandre uses meta tags to define base64 encoded images: <meta name="cid" HttpEq="image/*" content="base64">, so any <img src="cid"> will display that image. (Sérgio Alexandre)
• Virtual method TFVBase.DoGetImage added analog to THtmlViewer.DoGetImage. All viewers will use it, and it triggers the event. (Sérgio Alexandre)
• PostRequest is virtual now, descendants can provide internally any resource. (Sérgio Alexandre)
• Virtual method TFrameBrowser.AssertCanPostRequest extracted from LoadURLInternal. Descendants that override PostRequest may not require OnGetPostRequest* events and if so they must override AssertCanPostRequest as well. (Sérgio Alexandre)
• BeginProcessing, EndProcessing promoted to virtual, same purpose like InitLoad. (Sérgio Alexandre)
• Since "GetViewerClass" is virtual, "CreateViewer" is now virtual. E.g. Sérgio Alexandre uses it to remove borders. (Sérgio Alexandre)
• GDIPL2A.pas - Loading png-files no longer produces temporary files. Using IStreams instead.
• Property TViewerBase.UseQuirksMode replaces the definable symbol "Quirk". THtmlViewer now can decide to use the quirks mode depending on document. (J. Peter Mugaas)

• A bug where background images might not load if a path name contains spaces. (J. Peter Mugaas)
• When printing, do not show background if PrintBackground is False. This was happening when drawing a block. (J. Peter Mugaas)

• TBuffer.PeekChar did not reset the JIS state.
