SunliandJason Lee ccfc1ce387 gpui: Fix drawing rotated SVGs (#33288)
Fixes: https://github.com/longbridge/gpui-component/issues/994

1. When SVG is rotated, incorrect graphics are drawn.

For example: the original aspect ratio of the SVG is 1:1, if the bounds
used to render the SVG are 400x200 (aspect ratio 2:1),
[here](https://github.com/zed-industries/zed/blob/21f985a018f7cca9c0fb7f5b7a87555486ab9db5/crates/gpui/src/svg_renderer.rs#L91)
the width is used as the scaling factor, causing the rendered SVG to
only have half the height. This PR ensures the complete SVG image is
always rendered.

2. The clipping region has no transformation applied, I added a function
called `distance_from_clip_rect_transformed` in the shader.

3. Fixed `monochrome_sprite_fragment` in `shader.metal` not applying
clipping region.

Licensing

License information for third party dependencies must be correctly provided for CI to pass.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.
