Functions
int	KODI::VIDEO::GEOMETRY::NormaliseRotation (int degrees)
	degrees reduced to a quarter turn; anything else is upright.
CRect	KODI::VIDEO::GEOMETRY::Rotate (const CRect &rect, const CRect &frame, int orientation)
	Turn rect clockwise within frame, both upright and at the origin.
float	KODI::VIDEO::GEOMETRY::AspectOf (const CRect &rect)
int	KODI::VIDEO::GEOMETRY::EdgeDistance (const CRectInt &a, const CRectInt &b)
	Chebyshev distance between two rectangles: the furthest any single edge has moved.
bool	KODI::VIDEO::GEOMETRY::EdgesWithin (const CRectInt &a, const CRectInt &b, unsigned int tolerance)
	Are these the same boundary within tolerance, edge for edge?
CRect	KODI::VIDEO::GEOMETRY::FractionOf (const CRect &rect, const CRect &frame)
	rect as fractions of frame.
CRect	KODI::VIDEO::GEOMETRY::FromFraction (const CRect &fraction, const CRect &frame)
	The rectangle fraction describes within frame - FractionOf()'s inverse.
CRectInt	KODI::VIDEO::GEOMETRY::StereoViewRect (std::string_view stereoMode, unsigned int width, unsigned int height)
	The first view of a packed stereoscopic frame, or an empty rectangle for mono.
CRectInt	KODI::VIDEO::GEOMETRY::MeasuredFrameRect (std::string_view stereoMode, unsigned int width, unsigned int height)
	The region a measurement describes: one view of a packed frame, else the whole.
CRectInt	KODI::VIDEO::GEOMETRY::ScaleRect (const CRectInt &rect, unsigned int fromWidth, unsigned int fromHeight, unsigned int toWidth, unsigned int toHeight)
	rect read in one coordinate space, expressed in another of the same shape.
StreamGeometry	KODI::VIDEO::GEOMETRY::MeasuredStreamGeometry (std::string_view stereoMode, unsigned int width, unsigned int height, float displayAspect)
	What a measurement of a playing stream is expressed against, displayAspect being the ratio the whole packed frame is displayed at.
float	KODI::VIDEO::GEOMETRY::PixelAspectRatio (const StreamGeometry &stream)
	Width of a coded pixel in display pixels; 1 when the stream declares no ratio.
CRect	KODI::VIDEO::GEOMETRY::ToSquarePixels (const CRectInt &coded, const StreamGeometry &stream)
	Undo the coding's pixel aspect, leaving the picture oriented as it was coded.
CRect	KODI::VIDEO::GEOMETRY::FitAspect (float aspect, const CRect &frame)
	The largest rectangle of ratio aspect that fits centred inside frame.
bool	KODI::VIDEO::GEOMETRY::DescribesFrame (const RenderGeometry &geometry, const CRect &frameSource)
	Whether geometry was resolved from a frame of frameSource's shape.
CRect	KODI::VIDEO::GEOMETRY::SourceRect (const RenderGeometry &geometry, const CRect &frameSource)
	The part of frameSource holding content, in its own coordinates.
ContentCut	KODI::VIDEO::GEOMETRY::CutToContent (const RenderGeometry &geometry, const CRectInt &content, const CRect &frameSource)
	frameSource cut to content, a rectangle measured from one frame in the space of RenderGeometry::codedFrame. The pixel aspect and rotation come from geometry.
