- Rects snap to stage edge when within a threshold (10 screen pixels)
- When mouse leaves stage, set last mousedown pos to null, preventing nonfunctional rect outlines
Partially addresses #6306.
There's a technical challenge to fully address the issue - mouse event are not fired when the mouse is outside the stage. While we could draw the rect even if the mouse leaves, we cannot update the rect's dimensions on mouse move, or complete the drawing on mouse up.
To fully address the issue, we'd need to a way to forward window events back to the stage, or at least handle window events. We can explore this later.
When invoking with control layers, we were creating and uploading the mask images on every enqueue, even when the mask didn't change. The mask image can be cached to greatly reduce the number of uploads.
With this change, we are a bit smarter about the mask images:
- Check if there is an uploaded mask image name
- If so, attempt to retrieve its DTO. Typically it will be in the RTKQ cache, so there is no network request, but it will make a network request if not cached to confirm the image actually exists on the server.
- If we don't have an uploaded mask image name, or the request fails, we go ahead and upload the generated blob
- Update the layer's state with a reference to this uploaded image for next time
- Continue as before
Any time we modify the mask (drawing/erasing, resetting the layer), we invalidate that cached image name (set it to null).
We now only upload images when we need to and generation starts faster.
When recalling metadata and/or using control image dimensions, it was possible to set a width or height that was not a multiple of 8, resulting in generation failures.
Added a `clamp` option to the w/h actions to fix this. The option is used for all untrusted sources - everything except for the w/h number inputs, which clamp the values themselves.
Firefox v125.0.3 and below has a bug where `mouseenter` events are fired continually during mouse moves. The issue isn't present on FF v126.0b6 Developer Edition. It's not clear if the issue is present on FF nightly, and we're not sure if it will actually be fixed in the stable v126 release.
The control layers drawing logic relied on on `mouseenter` events to create new lines, and `mousemove` to extend existing lines. On the affected version of FF, all line extensions are turned into new lines, resulting in very poor performance, noncontiguous lines, and way-too-big internal state.
To resolve this, the drawing handling was updated to not use `mouseenter` at all. As a bonus, resolving this issue has resulted in simpler logic for drawing on the canvas.
- Add set of metadata handlers for the control layers CAs
- Use these conditionally depending on the active tab - when recalling on txt2img, the CAs go to control layers, else they go to the old CA area.
