Browser Webview (#1486)
* WebView: Add initial controller Co-authored-by: Mitchell Syer <Syer10@users.noreply.github.com> * WebView: Prepare page * WebView: Basic HTML setup * WebView: Improve navigation * WebView: Refactor message class deserialization * WebView: Refactor event message serialization * WebView: Handle click events * WebView: Fix events after refactor * WebView: Fix normalizing of URLs * WebView: HTML remove navigation buttons * WebView: Handle more events * WebView: Handle document change in events * WebView: Refactor to send mutation events * WebView: More mouse events * WebView: Include bubbles, cancelable in event Those seem to be important * WebView: Attempt to support nested iframe * WebView: Handle long titles * WebView: Avoid setting invalid url * WebView: Send mousemove * WebView: Start switch to canvas-based render * WebView: Send on every render * WebView: Dynamic size * WebView: Keyboard events * WebView: Handle mouse events in CEF This is important because JS can't click into iFrames, meaning the previous solution doesn't work for captchas * WebView: Cleanup * WebView: Cleanup 2 * WebView: Document title * WebView: Also send title on address change * WebView: Load and flush cookies from store * WebView: remove outdated TODOs * Offline WebView: Load cookies from store * Cleanup * Add KcefCookieManager, need to figure out how to inject it * ktLintFormat * Fix a few cookie bugs * Fix Webview on Windows * Minor cleanup * WebView: Remove /tmp image write, lint * Remove custom cookie manager * Multiple cookie fixes * Minor fix * Minor cleanup and add support for MacOS meta key * Get enter working * WebView HTML: Make responsive for mobile pages * WebView: Translate touch events to mouse scroll * WebView: Overlay an actual input to allow typing on mobile Browsers will only show the keyboard if an input is focused. This also removes the `tabstop` hack. * WebView: Protect against occasional NullPointerException * WebView: Use float for clientX/Y * WebView: Fix ChromeAndroid being a pain * Simplify enter fix * NetworkHelper: Fix cache * Improve CookieStore url matching, fix another cookie conversion issue * Move distinctBy * WebView: Mouse direction toggle * Remove accidentally copied comment --------- Co-authored-by: Mitchell Syer <Syer10@users.noreply.github.com>
