There's a Konva bug where `pointerenter` & `pointerleave` events aren't fired correctly on the stage.
In 87fdea4cc6 I made a change that surfaced this bug, breaking touch and Apple Pencil interactions, because the cursor position doesn't get updated.
Simple fix - ensure we update the cursor on `pointerdown` events, even though we shouldn't need to.
Will make a bug report upstream
- Set an empty title to prevent browsers from showing "Please match the requested format." when hovering the number input
- Fix issue w/ `z-index` that prevented the popover button from being clicked while the input was focused
The color picker take some time to sample the color from the canvas state. This could cause a race condition where the cursor position changes between the time sampling starts, resulting in the picker showing the wrong color. Sometimes it picks up the color picker tool preview!
To resolve this, the color picker's color syncing is now throttled to once per animation frame. Besides fixing the incorrect color issue, it improves the perf substantially by reducing number of samples we take.
- Record both absolute and relative positions
- Use simpler method to get relative position
- Generalize getColorUnderCursor to be getColorAtCoordinate
A new "session" just means to reset most settings to default values, excluding model.
There are a few things that need to be reset:
- Parameters state, except for models and things dependent on model selection (like VAE precision)
- Canvas state, except for the `modelBase`, which is dependent on the model selection
- Canvas staging area state
- LoRAs state
- HRF state
- Style presets state
We also select the canvas tab.
For new gallery sessions, we:
- Open the image viewer
- Set the right panel tab to `gallery`
And for new canvas sessions, we:
- Close the image viewer
- Set the right panel tab to `layers`
