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.

// |-terminate:| is the entry point for orderly "quit" operations in Cocoa. This
// includes the application menu's quit menu item and keyboard equivalent, the
// application's dock icon menu's quit menu item, "quit" (not "force quit") in
// the Activity Monitor, and quits triggered by user logout and system restart
// and shutdown.
//
// The default |-terminate:| implementation ends the process by calling exit(),
// and thus never leaves the main run loop. This is unsuitable for Chromium
// since Chromium depends on leaving the main run loop to perform an orderly
// shutdown. We support the normal |-terminate:| interface by overriding the
// default implementation. Our implementation, which is very specific to the
// needs of Chromium, works by asking the application delegate to terminate
// using its |-tryToTerminateApplication:| method.
//
// |-tryToTerminateApplication:| differs from the standard
// |-applicationShouldTerminate:| in that no special event loop is run in the
// case that immediate termination is not possible (e.g., if dialog boxes
// allowing the user to cancel have to be shown). Instead, this method tries to
// close all browsers by calling CloseBrowser(false) via
// ClientHandler::CloseAllBrowsers. Calling CloseBrowser will result in a call
// to ClientHandler::DoClose and execution of |-performClose:| on the NSWindow.
// DoClose sets a flag that is used to differentiate between new close events
// (e.g., user clicked the window close button) and in-progress close events
// (e.g., user approved the close window dialog). The NSWindowDelegate
// |-windowShouldClose:| method checks this flag and either calls
// CloseBrowser(false) in the case of a new close event or destructs the
// NSWindow in the case of an in-progress close event.
// ClientHandler::OnBeforeClose will be called after the CEF NSView hosted in
// the NSWindow is dealloc'ed.
//
// After the final browser window has closed ClientHandler::OnBeforeClose will
// begin actual tear-down of the application by calling CefQuitMessageLoop.
// This ends the NSApplication event loop and execution then returns to the
// main() function for cleanup before application termination.
//
// The standard |-applicationShouldTerminate:| is not supported, and code paths
// leading to it must be redirected.
