chrome: Add support for Alloy style browsers and windows (see #3681) Split the Alloy runtime into bootstrap and style components. Support creation of Alloy style browsers and windows with the Chrome runtime. Chrome runtime (`--enable-chrome-runtime`) + Alloy style (`--use-alloy-style`) supports Views (`--use-views`), native parent (`--use-native`) and windowless rendering (`--off-screen-rendering-enabled`). Print preview is supported in all cases except with windowless rendering on all platforms and native parent on MacOS. It is disabled by default with Alloy style for legacy compatibility. Where supported it can be enabled or disabled globally using `--[enable|disable]-print-preview` or configured on a per-RequestContext basis using the `printing.print_preview_disabled` preference. It also behaves as expected when triggered via the PDF viewer print button. Chrome runtime + Alloy style behavior differs from Alloy runtime in the following significant ways: - Supports Chrome error pages by default. - DevTools popups are Chrome style only (cannot be windowless). - The Alloy extension API will not supported. Chrome runtime + Alloy style passes all expected Alloy ceftests except the following: - `DisplayTest.AutoResize` (Alloy extension API not supported) - `DownloadTest.*` (Download API not yet supported) - `ExtensionTest.*` (Alloy extension API not supported) This change also adds Chrome runtime support for CefContextMenuHandler::RunContextMenu (see #3293). This change also explicitly blocks (and doesn't retry) FrameAttached requests from PDF viewer and print preview excluded frames (see #3664). Known issues specific to Chrome runtime + Alloy style: - DevTools popup with windowless rendering doesn't load successfully. Use windowed rendering or remote debugging as a workaround. - Chrome style Window with Alloy style BrowserView (`--use-alloy-style --use-chrome-style-window`) does not show Chrome theme changes. To test: - Run `ceftests --enable-chrome-runtime --use-alloy-style [--use-chrome-style-window] [--use-views|--use-native] --gtest_filter=...` - Run `cefclient --enable-chrome-runtime --use-alloy-style [--use-chrome-style-window] [--use-views|--use-native|--off-screen-rendering-enabled]` - Run `cefsimple --enable-chrome-runtime --use-alloy-style [--use-views]`

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.
