wasm: support rendering to multiple canvases
Qt (via the the qtloader.js API) now supports rendering to multiple canvases. The application sees each canvas as a QScreen. Make qtloader.js support multiple canvases: var qtloader = QtLoader({ canvasElements : [array-of-canvas], showCanvas: function() { // make canvas(es) visible }, }); The canvases were previously created/returned by showCanvas(), however this function is called after the Qt app has been started and adding screens that that point is too late. (This worked before since there was only one screen, and no need to connect each screen instance to specific canvas.) Remove QWasmScreen, QWasmCompositor, and QWasmEventTranslator singletons from QWasmIntegration. These are are now crated per-screen and are owned by the QWasmScreen. Task-number: QTBUG-64079 Change-Id: I24689929fd5bfb7ff0ba076f66937728fa4bc4e4 Reviewed-by: Lorn Potter <lorn.potter@gmail.com>
