* | wasm: store and pass canvases as emscripten::valMorten Johan Sørvig2020-02-128-59/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Store and pass canvases as emscripten::val instead of a QString containing the element id. This simplifies code which interacts with the canvas using the emscripten::val API, by removing the need to look up with getElementById. The Emscripten C event API does not accept emscripten::val, and using the element id is still needed here. emscripten::val does not provide a hash key suitable for use with QHash, but does provide an equality-compare in the form of val::equals(). Change the canvas->screen mapping code to use a QVector instead of a QHash. Change-Id: I1dbdbbc8fb06bb869031f1500e83ae2d64780a7f Reviewed-by: Lorn Potter <lorn.potter@gmail.com>

Both eglfs and wasm lack the concept of true raster windows. A QWindow with RasterSurface is rendered with OpenGL no matter what. The two platforms took two different approaches to work around the rest of the machinery: - wasm disabled the QOpenGLContext warning for non-OpenGL QWindows, - eglfs forced the QWindow surfaceType to OpenGLSurface whenever it was originally set to RasterSurface. Now, the latter breaks since c4e9eabc309a275efc222f4127f31ba4677259b7, leaving all raster window applications failing on eglfs, because flush in the backingstore is now checking the surface type and disallows OpenGLSurface windows. (just like how QOpenGLContext disallows RasterSurface windows) To solve all this correctly, introduce a new platform capability, OpenGLOnRasterSurface, and remove the special handling in the platform plugins.
