//!  Primitive segmentation
//!
//! # Overview
//!
//! Segmenting is the process of breaking rectangular primitives into smaller rectangular
//! primitives in order to extract parts that could benefit from a fast paths.
//!
//! Typically this is used to allow fully opaque segments to be rendered in the opaque
//! pass. For example when an opaque rectangle has a non-axis-aligned transform applied,
//! we usually have to apply some anti-aliasing around the edges which requires alpha
//! blending. By segmenting the edges out of the center of the primitive, we can keep a
//! large amount of pixels in the opaque pass.
//! Segmenting also lets us avoids rasterizing parts of clip masks that we know to have
//! no effect or to be fully masking. For example by segmenting the corners of a rounded
//! rectangle clip, we can optimize both rendering the mask and the primitive by only
//! rasterize the corners in the mask and not applying any clipping to the segments of
//! the primitive that don't overlap the borders.
//!
//! It is a flexible system in the sense that different sources of segmentation (for
//! example two rounded rectangle clips) can affect the segmentation, and the possibility
//! to segment some effects such as specific clip kinds does not necessarily mean the
//! primitive will actually be segmented.
//!
//! ## Segments and clipping
//!
//! Segments of a primitive can be either not clipped, fully clipped, or partially clipped.
//! In the first two case we don't need a clip mask. For each partially masked segments, a
//! mask is rasterized using a render task. All of the interesting steps happen during frame
//! building.
//!
//! - The first step is to determine the segmentation and write the associated GPU data.
//!   See `PrimitiveInstance::build_segments_if_needed` and `write_brush_segment_description`
//!   in `prim_store/mod.rs` which uses the segment builder of this module.
//! - The second step is to generate the mask render tasks.
//!   See `BrushSegment::update_clip_task` and `RenderTask::new_mask`. For each segment that
//!   needs a mask, the contribution of all clips that affect the segment is added to the
//!   mask's render task.
//! - Segments are assigned to batches (See `batch.rs`). Segments of a given primitive can
//!   be assigned to different batches.
//!
//! See also the [`clip` module documentation][clip.rs] for details about how clipping
//! information is represented.
