Struct RenderFrame 

pub struct RenderFrame {
    pub atlas_dirty: bool,
    pub atlas_width: u32,
    pub atlas_height: u32,
    pub atlas_pixels: Vec<u8>,
    pub glyphs: Vec<GlyphQuad>,
    pub images: Vec<ImageQuad>,
    pub decorations: Vec<DecorationRect>,
    /* private fields */
}

Everything needed to draw one frame.

Produced by crate::Typesetter::render. Contains glyph quads (textured rectangles from the atlas), inline image placeholders, and decoration rectangles (selections, cursor, underlines, table borders, etc.).

The adapter draws the frame in three passes:

1. Upload atlas_pixels as a GPU texture (only when atlas_dirty is true).
2. Draw each GlyphQuad as a textured rectangle from the atlas.
3. Draw each DecorationRect as a colored rectangle.

Fields

atlas_dirty: bool

True if the atlas texture changed since the last frame (needs re-upload).

atlas_width: u32

Atlas texture width in pixels.

atlas_height: u32

Atlas texture height in pixels.

atlas_pixels: Vec<u8>

RGBA pixel data, row-major. Length = atlas_width * atlas_height * 4.

glyphs: Vec<GlyphQuad>

One textured rectangle per visible glyph.

images: Vec<ImageQuad>

Inline image placeholders. The adapter loads the actual image data (e.g., via TextDocument::resource(name)) and draws it at the given screen position.

decorations: Vec<DecorationRect>

Decoration rectangles: selections, cursor, underlines, strikeouts, overlines, backgrounds, table borders, and cell backgrounds.
