Data Fields
Vector4< int >	viewportXywh

float	fov
	posX, posY, width, height

bool	gravityLabels
	FOV in degrees.

float	defaultAngleForGravityText
	the flag to use gravity labels or not

StelProjectorMaskType	maskType
	a rotation angle to apply to gravity text (only if gravityLabels is set to false)

float	zNear
	The current projector mask.

float	zFar

Vec2f	viewportCenter
	Near and far clipping planes.

Vec2f	viewportCenterOffset
	Viewport center in screen pixel.

float	viewportFovDiameter
	Viewport center's offset in fractions of screen width/height. More...

bool	flipHorz
	diameter of the FOV disk in pixel

bool	flipVert

float	devicePixelsPerPixel
	Whether to flip in horizontal or vertical directions.

float	widthStretch
	The number of device pixel per "Device Independent Pixels" (value is usually 1, but 2 for mac retina screens)

float StelProjector::StelProjectorParams::viewportFovDiameter

Usable e.g. in cylindrical projection to move horizon down. Currently only Y shift is fully implemented, X shift likely not too meaningful.
