}

All render pipelines, bind-group layouts, and shared samplers.

Created once per crate::WgpuGfxCtx and reused for the lifetime of the context. The struct is publicly visible so library primitives like crate::ssaa::SsaaFramebuffer::blit_to can take a reference and reuse the shared 2-D textured-quad pipeline; the fields themselves stay pub(crate) so external code can hold a &WgpuPipelines but cannot reach in and rebuild individual pipelines.

solid_bgl: BindGroupLayout

aa_solid_pipeline: RenderPipeline

aa_solid_bgl: BindGroupLayout

aa_texture_pipeline: RenderPipeline

aa_texture_bgl0: BindGroupLayout

aa_texture_bgl1: BindGroupLayout

gradient_pipeline: RenderPipeline

gradient_bgl0: BindGroupLayout

gradient_bgl1: BindGroupLayout

tex_pipeline: RenderPipeline

tex_bgl0: BindGroupLayout

tex_bgl1: BindGroupLayout

tex_downsample_3x_pipeline: RenderPipeline

Same vertex / bind groups as tex_pipeline; fragment shader runs 9 point-aligned taps at {-1, 0, +1}² texel offsets for an exact 3×3 box average. Used by the cube widget at the 9× SSAA setting where a single bilinear minification would drop 5 of 9 source texels per output pixel (visually indistinguishable from no AA).

tex_downsample_4x_pipeline: RenderPipeline

Same vertex / bind groups as tex_pipeline; fragment shader runs 4 bilinear taps in a 2×2 quadrant grid for an exact 4×4 box average. Used by the cube widget at the highest SSAA setting where a single bilinear minification would drop 12 of 16 source texels per output.

layer_pipeline: RenderPipeline

layer_mesh_pipeline: RenderPipeline

Masked variant of layer_pipeline: composites a clip layer through the tessellated clip path (pos2 + uv2 + coverage). Built in crate::layer_mask, which also owns its shader.

layer_bgl0: BindGroupLayout

layer_bgl1: BindGroupLayout

lcd_r: RenderPipeline

lcd_g: RenderPipeline

lcd_b: RenderPipeline

lcd_bgl0: BindGroupLayout

lcd_bgl1: BindGroupLayout

lcb_r: RenderPipeline

lcb_g: RenderPipeline

lcb_b: RenderPipeline

lcb_bgl0: BindGroupLayout

lcb_bgl1: BindGroupLayout

text_gray: RenderPipeline

Grayscale coverage text quad — reuses the LCD bind-group layouts but writes ALL colour channels + alpha in one pass. Routed to when text is drawn inside a compositing layer so the layer texture gets correct alpha (the 3-pass LCD pipelines never write alpha → washed-out glyphs on pop).

lcb_flatten: RenderPipeline

Two-plane backbuffer flatten quad — reuses the LCB bind-group layouts, collapses the per-channel planes into a single premultiplied sample in one alpha-writing pass. Inside-layer companion to lcb_r/g/b.

nearest_sampler: Sampler

Nearest-neighbour — used for LCD mask textures and Label backbuffers.

linear_sampler: Sampler

Bilinear — used for images, layers, and gradient ramp textures.
