Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request resolves a visual bug where the origin pivot gizmo could appear misaligned within the editor. The fix ensures that the gizmo's viewport position is accurately computed by applying a transformation that correctly considers the specific layer it is associated with, thereby eliminating the misalignment.

Highlights

• Origin Pivot Gizmo Alignment: Corrected the calculation of the viewport origin for the origin pivot gizmo by utilizing a layer-specific downstream transformation, resolving a potential misalignment issue.

Changelog

• editor/src/messages/tool/common_functionality/graph_modification_utils.rs
  • Updated the get_viewport_origin function to use downstream_transform_to_viewport(layer) instead of document_to_viewport for more accurate coordinate transformation.

Code Review

This pull request fixes a bug where the origin pivot gizmo could be misaligned for nested layers. The change correctly uses downstream_transform_to_viewport to account for the full transformation hierarchy of parent layers when calculating the origin's viewport position. The previous implementation using document_to_viewport was incorrect for nested layers as it did not account for parent transforms. The fix is correct and addresses the described issue.

I don't know if its a bug or glitch of my browser but sometimes the rotate icons got disappear as you can see in the video.
If its a bug kindly check it once else ignore.
Thankyou.
