Implement off-screen rendering support using delegated rendering (issue #1257). This implementation supports both GPU compositing and software compositing (used when GPU is not supported or when passing `--disable-gpu --disable-gpu-compositing` command-line flags). GPU-accelerated features (WebGL and 3D CSS) that did not work with the previous off-screen rendering implementation do work with this implementation when GPU support is available. Rendering now operates on a per-frame basis. The frame rate is configurable via CefBrowserSettings.windowless_frame_rate up to a maximum of 60fps (potentially limited by how fast the system can generate new frames). CEF generates a bitmap from the compositor backing and passes it to CefRenderHandler::OnPaint. The previous CefRenderHandler/CefBrowserHost API for off-screen rendering has been restored mostly as-is with some minor changes: - CefBrowserHost::Invalidate no longer accepts a CefRect region argument. Instead of invalidating a specific region it now triggers generation of a new frame. - The |dirtyRects| argument to CefRenderHandler::OnPaint will now always be a single CefRect representing the whole view (frame) size. Previously, invalidated regions were listed separately. - Linux: CefBrowserHost::SendKeyEvent now expects X11 event information instead of GTK event information. See cefclient for an example of converting GTK events to the necessary format. - Sizes passed to the CefRenderHandler OnPaint and OnPopupSize methods are now already DPI scaled. Previously, the client had to perform DPI scaling. - Includes drag&drop implementation from issue #1032. - Includes unit test fixes from issue #1245. git-svn-id: https://chromiumembedded.googlecode.com/svn/trunk@1751 5089003a-bbd8-11dd-ad1f-f1f9622dbc98

Implement Views framework on Windows and Linux (issue #1749). - Add Views header files in a new include/views directory. - Add initial top-level window (CefWindow), control (CefBrowserView, CefLabelButton, CefMenuButton, CefPanel, CefScrollView, CefTextfield) and layout (CefBoxLayout, CefFlowLayout) support. See libcef/browser/views/view_impl.h comments for implementation details. - Add Views example usage in cefclient and cefsimple and Views unit tests in cef_unittests. Pass the `--use-views` command-line flag to cefclient, cefsimple and cef_unittests to run using the Views framework instead of platform APIs. For cefclient and cefsimple this will create the browser window and all related functionality using the Views framework. For cef_unittests this will run all tests (except OSR tests) in a Views-based browser window. Views- specific unit tests (`--gtest_filter=Views*`) will be run even if the the `--use-views` flag is not specified. - Pass the `--hide-frame` command-line flag to cefclient to demo a frameless Views-based browser window. - Pass the `--hide-controls` command-line flag to cefclient to demo a browser window without top controls. This also works in non-Views mode. - Pass the `--enable-high-dpi-support` command-line flag to cef_unittests on Windows to test high-DPI support on a display that supports it. - Add CefImage for reading/writing image file formats. - Add CefBrowser::DownloadImage() for downloading image URLs as a CefImage representation. This is primarily for loading favicons. - Add CefMenuModel::CreateMenuModel() and CefMenuModelDelegate for creating custom menus. This is primarily for use with CefMenuButton. - Add CefBrowser::TryCloseBrowser() helper for closing a browser. Also improve related documentation in cef_life_span_handler.h. - Rename cef_page_range_t to cef_range_t. It is now also used by CefTextfield. - Remove CefLifeSpanHandler::RunModal() which is never called. - Add draggable regions example to cefclient.
