Struct Pane 

pub struct Pane { /* private fields */ }

wgpu renderer for a single render target.

Operates in two modes:

• Overlay — created with Pane::new; the caller owns the surface and supplies a GpuFrame each call to Pane::render.
• Standalone — created internally by run; Pane owns the window, surface, device, and queue and drives its own event loop.

Implementations

impl Pane

pub fn new(device: &Device, queue: &Queue, format: TextureFormat) -> Self

Create for overlay mode — caller provides device/queue.

pub fn register_shader( &mut self, device: &Device, wgsl: &str, tex_reg: &TextureRegistry, ) -> ShaderId

Compile a WGSL shader and register it as a render pipeline, returning its ShaderId.

Results are cached by source string, so calling this with the same WGSL twice is free. The pipeline is configured for the vertex layout used by Scene: positions, UVs, colour, corner radius / border width, widget size, and widget state.
