Classes
struct	KIGFX::RETAINED_GROUP_ORDER
struct	KIGFX::GRID_SOURCE
	Render-time projection of a grid: GRID_GEOMETRY (kind/origin/pitch/orientation/extent) plus rendering and interaction flags. More...
class	KIGFX::GAL
	Abstract interface for drawing on a 2D-surface. More...
struct	KIGFX::GAL::GRID_LATTICE
	The spacing of a grid source's lattice as it is drawn at the current zoom. More...
class	KIGFX::GAL_CONTEXT_LOCKER
class	KIGFX::GAL_UPDATE_CONTEXT
class	KIGFX::GAL_DRAWING_CONTEXT
class	KIGFX::GAL_SCOPED_ATTRS
	Attribute save/restore for GAL attributes. More...

Namespaces
namespace	KIGFX
	The Cairo implementation of the graphics abstraction layer.

Enumerations
enum class	KIGFX::GAL_CONTEXT_LOSS { KIGFX::NONE , KIGFX::RECOVERABLE , KIGFX::REPEATED }
	State of a canvas' rendering context after a GPU reset. More...

Functions
double	KIGFX::AutoSparsePitch (double aPitch, unsigned aTick, double aThreshold)
	Multiply aPitch by aTick until it exceeds aThreshold, so a sub-threshold grid still shows every Nth line.

Variables
constexpr double	KIGFX::GRID_DIM_ALPHA = 0.4
	Opacity of the background wash laid over a selected grid item's area, to fade the grids showing through it.
constexpr double	KIGFX::GRID_EDGE_DARKEN = 0.75
	How far the hairline round a grid's coverage sits below its own colour.
constexpr double	KIGFX::GRID_SELECTED_BRIGHTEN = 0.5
	How far the grid being edited is lifted above its own colour.
