The `ViewportTurboRendererExtension` is now extracted from `@blocksuite/affine-shared` to `@blocksuite/affine-gfx-turbo-renderer` with minimal dependencies, mirroring the gfx text package in #10378.
Currently, `GfxViewportElement` hides DOM blocks outside the viewport using `display: none` to optimize performance. However, this approach presents two issues:
1. Even when hidden, all top-level blocks still undergo frequent CSS transform updates during viewport panning and zooming.
2. Hidden blocks cannot access DOM layout information, preventing `TurboRenderer` from updating the complete canvas bitmap.
To address this, this PR introduces a refactoring that divides all top-level edgeless blocks into two states: `idle` and `active`. The improvements are as follows:
1. Blocks outside the viewport are set to the `idle` state, meaning they no longer update their DOM during viewport panning or zooming. Only `active` blocks within the viewport are updated frame by frame.
2. For `idle` blocks, the hiding method switches from `display: none` to `visibility: hidden`, ensuring their layout information remains accessible to `TurboRenderer`.

While this minimizes DOM updates, it introduces a trade-off: `idle` blocks retain an outdated layout state. Since their positions are updated using a lazy update strategy, their layout state remains frozen at the moment they were last moved out of the viewport:
To resolve this, the PR serializes and stores the viewport field of the block at that moment on the `idle` block itself. This allows the correct layout, positioned in the model coordinate system, to be restored from the stored data.
This PR performs a significant architectural refactoring by extracting rich text functionality into a dedicated package. Here are the key changes:
1. **New Package Creation**
- Created a new package `@blocksuite/affine-rich-text` to house rich text related functionality
- Moved rich text components, utilities, and types from `@blocksuite/affine-components` to this new package
2. **Dependency Updates**
- Updated multiple block packages to include the new `@blocksuite/affine-rich-text` as a direct dependency:
- block-callout
- block-code
- block-database
- block-edgeless-text
- block-embed
- block-list
- block-note
- block-paragraph
3. **Import Path Updates**
- Refactored all imports that previously referenced rich text functionality from `@blocksuite/affine-components/rich-text` to now use `@blocksuite/affine-rich-text`
- Updated imports for components like:
- DefaultInlineManagerExtension
- RichText types and interfaces
- Text manipulation utilities (focusTextModel, textKeymap, etc.)
- Reference node components and providers
4. **Build Configuration Updates**
- Added references to the new rich text package in the `tsconfig.json` files of all affected packages
- Maintained workspace dependencies using the `workspace:*` version specifier
The primary motivation appears to be:
1. Better separation of concerns by isolating rich text functionality
2. Improved maintainability through more modular package structure
3. Clearer dependencies between packages
4. Potential for better tree-shaking and bundle optimization
This is primarily an architectural improvement that should make the codebase more maintainable and better organized.
