Module primitives

CPU vertex builders and scissor encoding for renderer primitives.

Functions

apply_layer_scissor

Applies the layer scissor, or resets to the full surface when there is no clip.

make_tex_rect

Builds a full-UV image quad at DPR 1.

make_tex_rect_scaled

Builds a full-UV image quad after scaling logical bounds to physical pixels.

now_ms

Returns Unix epoch time in whole milliseconds.

push_border_rrect_scaled

Appends a rounded-border SDF quad in physical-pixel geometry.

push_box_shadow_scaled

Appends a paint-only outer box-shadow SDF quad.

push_rect

Appends a solid logical-pixel rectangle at DPR 1.

push_rect_scaled

Appends a solid rectangle after scaling logical geometry to physical pixels.

push_ring_progress_scaled

Appends a circular-progress SDF quad in physical-pixel geometry.

push_rrect

Appends a rounded-rectangle SDF quad at DPR 1.

push_rrect_scaled

Appends a rounded-rectangle SDF quad in physical-pixel geometry.

push_text

Appends textured glyph quads at DPR 1 using a complete atlas frame cycle.

push_text_scaled

Appends textured glyph quads for an already-started atlas frame.

set_scissor_rect

Applies one logical scissor rectangle at DPR 1.

set_scissor_rect_scaled

Snaps a logical scissor outward at DPR and applies its nonempty intersection.

to_ndc

Converts top-left-origin physical pixels to wgpu normalized device coordinates.
