Mask vector data includes additive (brush, rect) shapes and subtractive (eraser) shapes. A different composite operation is used to draw a shape, depending on whether it is additive or subtractive.
This means that a mask may have vector objects, but once rendered, is _visually_ empty (fully transparent). The only way determine if a mask is visually empty is to render it and check every pixel.
When we generate and save layer metadata, these fully erased masks are still used. Generating with an empty mask is a no-op in the backend, so we want to avoid this and not pollute graphs/metadata.
Previously, we did that pixel-based when calculating the bbox, which we only did when using the move tool, and only for the selected layer.
This change introduces a simpler function to check if a mask is transparent, and if so, deletes all its objects to reset it. This allows us skip these no-op layers entirely.
This check is debounced to 300 ms, trailing edge only.
- Viewer only exists on Generation tab
- Viewer defaults to open
- When clicking the Control Layers tab on the left panel, close the viewer (i.e. open the CL editor)
- Do not switch to editor when adding layers (this is handled by clicking the Control Layers tab)
- Do not open viewer when single-clicking images in gallery
- _Do_ open viewer when _double_-clicking images in gallery
- Do not change viewer state when switching between app tabs (this no longer makes sense; the viewer only exists on generation tab)
- Change the button to a drop down menu that states what you are currently doing, e.g. Viewing vs Editing
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.
- Revise control adapter config types
- Recreate all control adapter mutations in control layers slice
- Bit of renaming along the way - typing 'RegionalGuidanceLayer' over and over again was getting tedious
