This graph shows which files directly or indirectly include this file:

Classes
struct	donner::svg::compositor::ImmediateLayerPlan
	Immediate-mode eligibility and timing diagnostics for a promoted layer. More...
class	donner::svg::compositor::CompositorLayer
	Represents a single compositor layer with its cached bitmap and dirty state. More...

Namespaces
namespace	donner
	Top-level Donner namespace, which is split into different sub-namespaces such as donner::svg and donner::css.
namespace	donner::svg
	Donner SVG library, which can load, manipulate and render SVG files.

Enumerations

Functions
constexpr FallbackReason	donner::svg::compositor::operator| (FallbackReason a, FallbackReason b)
	Bitwise OR.
constexpr FallbackReason	donner::svg::compositor::operator& (FallbackReason a, FallbackReason b)
	Bitwise AND.
constexpr FallbackReason &	donner::svg::compositor::operator|= (FallbackReason &a, FallbackReason b)
	Bitwise OR assignment.
std::string	donner::svg::compositor::FallbackReasonToString (FallbackReason reasons)
	Format reasons as a pipe-separated list of set flag names, e.g. "Filter | IsolatedLayer". Returns "None" when no flags are set. Used by the editor's layer-inspector panel to render the "Kind" column.

FallbackReason

enum class donner::svg::compositor::FallbackReason : uint16_t

strong

Flags indicating which compositing features on a promoted entity require conservative fallback (full re-rasterization on every frame rather than bitmap caching).

Each flag corresponds to an SVG feature that cannot be correctly rendered in isolation when the entity is composited separately from the rest of the scene.

Enumerator
BlendMode	Entity has mix-blend-mode != normal, requiring interaction with backdrop.
Filter	Entity has a filter effect, which may reference sourceGraphic/BackgroundImage.
ClipPath	Entity has a clip-path referencing elements outside the promoted subtree.
Mask	Entity has a mask referencing elements outside the promoted subtree.
Markers	Entity has markers, whose rendering depends on the containing document context.
ExternalPaint	Entity has a paint server (gradient/pattern) referencing external elements.
IsolatedLayer	Entity establishes an isolation group (opacity < 1 composed with siblings).
