isolated compositor: draw-command bounds for isolated offscreen regions. Device-space bounds for draw commands (isolated compositor).

Constants

BLUR_PADDING_FACTOR

Padding multiplier for blur kernel (physical pixels).

Functions

inflate_for_effects

Inflates bounds for every blur in an isolated effect chain.

push_composite_quad

NDC quad for compositing an offscreen texture into destination rect.

push_composite_quad_local

NDC quad in local offscreen space (origin top-left of the pass).

scissor_to_local

Convert global physical scissor to local coordinates inside offscreen pass.

snap_and_clamp_bounds

Snaps physical bounds outward and clamps their far edges to a surface.

union_cmd_bounds

Union of axis-aligned bounds for all commands in a layer (physical pixels).

union_cmd_bounds_prepared

Computes command bounds using prepared glyph extents when available.
