Switch between workspaces with touchpad gestures

good catch - this was a pain in fade out animations haha

+	int x = 0, y = 0;
+
+	int ws_dimen;
+	int *coord;
+	switch (output->workspace_scroll.direction) {
+	case SWIPE_GESTURE_DIRECTION_NONE:
+		return;
+	case SWIPE_GESTURE_DIRECTION_HORIZONTAL:
+		ws_dimen = output->width;
+		coord = &x;
+		break;
+	case SWIPE_GESTURE_DIRECTION_VERTICAL:
+		ws_dimen = output->height;
+		coord = &y;
+		break;
+	}


this bit is confusing to me, may need some clarification - what do x and y represent if they remain at 0 - and why does coord depend on them?

Oh yeah, that is a bit confusing… xD

It's mostly there to remove duplicate code due to the gesture either needing to adjust the X or Y coordinates depending on the gesture direction. Do you have any other way of solving this without duplicating the code?

Maybe just add the x and y coords as args?

wouldn't clipping to the output size solve this? Maybe this comment is my lack of understanding of the purpose of x and y coming out 😅

That's exactly that it's doing, except that we're translating the damage to the workspaces translated bounds

sway/desktop/render.c

+	pixman_region32_t *damage, struct sway_container *con, bool parent_focused,
+	bool is_current_ws);


parent_focused, is_current_ws: can we combine these? I'd think they'd indicate the same thing and would clean up quite a few function calls

Not sure about this. The parent_focused sometimes indicates if the container is focused or not. Could result in some cases where an unfocused container in the focused workspace would be incorrectly adjusted as if it was located on the sibling workspace

sway/desktop/render.c

+	for (int i = 0; i < workspace->current.floating->length; ++i) {
+		struct sway_container *floater =
+			workspace->current.floating->items[i];
+		if (container_is_transient_for(floater, fullscreen_con)) {
+			render_floating_container(output, damage, floater, on_focused_workspace);
+		}
+	}


why do we render floating containers in this function? Wouldn't the fullscreen view be above floating cons?

This is for floating containers that are transient for the fullscreened application. It's what upstream does :)

Maybe something like this:

Looks good to me!

I'll wait with refining this until the sway 1.9 rebase is merged :)
