Bug 1581240 - Return collected frames as a promise to JS r=bzbarsky,mstange,nika The `setCompositionRecording` API on nsIDOMWindowUtils has been broken up into two new APIs: * `startCompositionRecording()`, which starts the composition recorder; and * `stopCompositionRecording(bool writeToDisk)` which stops the composition recorder and either returns a Promise that resolves to the collected frames or returns a Promise that resolves when the frames have been written to disk. The collected frames are serialized over IPC as part of a Shmem as to not approach the IPC data transfer limit. Differential Revision: https://phabricator.services.mozilla.com/D47818

Bug 1581240 - Return collected frames from the composition recorder as data URIs r=mstange The composition recorder can now either write frames to disk as PNGs or return the frames as an array of data URIs. This will allow us to send the collected frames across IPC and hand them over to JS in a later patch. Differential Revision: https://phabricator.services.mozilla.com/D47815

Bug 1581240 - Return a Promise from windowUtils.setCompositionRecording() r=nika `windowUtils.setCompositionRecording()` now returns a promise that is resolved when the composition recorder is enabled (if given `true`) or when frames are written to disk (if given `false`). To accomplish this, the `WebRenderCompositionRecorder` now returns a `MozPromise` when writing frames to disk begins that is resolved when that process finishes.

Bug 1570124 - Enable mouse scrolling in FxR window r=masayuki This change addresses two issues with vrhost sending WM_MOUSEWHEEL events: - The point from the message had an incorrect coordinate origin. Documentation specifices that it should be screen, rather than window/client, origin. Since vrhost only knows about a position in the window, it translates the point before sending the message. - Gecko ignores the point passed in to the window message and instead uses the point from GetMessagePos. As warnings indicate, this can be incorrect, as is exposed with vrhost. This change now uses this point from the message when available.

Bug 1594529: Infer nsDocShell::IsFrame from BrowsingContext. r=nika This fixes the content policy type for document loads in these frames, where the explicit mIsFrame flag was not set, due to DocShell creation taking a different code path in remote frames than in in-process frames.

Bug 1587539 - Skip bounds check when getting IAT if Import Directory is tampered. r=aklotz Some applications tamper Import Directory entry of a loaded executable image to pretend static dependency on their module. We have `RestoreImportDirectory` to revert it in the browser process. If tampering happened in the launcher process, however, we failed to get an IAT thunk address via `GetIATThunksForModule` because it could be located outside the mapped image. With this patch, we skip bounds check in `GetIATThunksForModule` if we detect tampering in the launcher process. We can proceed safely because it's expected that Import Directory is still valid though it's located outside. Differential Revision: https://phabricator.services.mozilla.com/D49690
