Windows taskbar progress support (#264) * Initial Windows taskbar progress support * Changes to COM (un)init It turns out winapi exposes IIDs through a `uuidof()` function of interfaces, so the copied one can be removed. * Don't return error codes Now the `TaskbarProgress` functions fail silently. The `TaskbarProgress` struct now will always be created (even in case of errors in initialisation), but it won't do anything. * Fix builds for other systems * Formatted code * Fix progress shown after the operation finished A progress update was received after the stop event. Also `as_ref()` was removed in many places (I don't even know why it was there). * Remove redundant call to hide It's already called by the `glib_stop_receiver` receiver. * Release the ITaskbarList3 and call CoUninitialize at exit Because objects moved to closures used as fallbacks in GTK have [static lifetimes](https://gtk-rs.org/docs-src/tutorial/closures#closures), the `TaskbarProgress` will never be dropped. To workaround this problem a `release` function is called when the main window is closed. This function behaves like `drop`, but sets the struct in a valid "empty" state, so that calling `release`/`drop` again won't cause problems. * Don't set the NORMAL state manually Because only NOPROGRESS and INDETERMINATE states are used, there is no need to set the NORMAL state when changing the progress value. Now `set_progress_value` will also change the `TaskbarProgress::current_state` if such situation occurs. > Unless [SetProgressState](https://docs.microsoft.com/en-us/windows/desktop/api/shobjidl_core/nf-shobjidl_core-itaskbarlist3-setprogressstate) > has set a blocking state (TBPF_ERROR or TBPF_PAUSED) for the window, a call to SetProgressValue assumes the TBPF_NORMAL > state even if it is not explicitly set. A call to SetProgressValue overrides and clears the TBPF_INDETERMINATE state. See the [SetProgressValue documentation](https://docs.microsoft.com/en-us/windows/win32/api/shobjidl_core/nf-shobjidl_core-itaskbarlist3-setprogressvalue#how-the-taskbar-button-chooses-the-progress-indicator-for-a-group) 2021-02-21 00:24:36 +13:00			`#[cfg(not(target_os = "windows"))]`
