- Removed the Graphics32 dependency in SimpleOSRBrowser demo. Now this demo uses a custom component called TBufferPanel included in CEF4Delphi. - Now SimpleOSRBrowser demo draws the "select" elements. - Fixed a bug in SimpleOSRBrowser with high DPI monitors. The new paint function works with all client sizes.
