Public Member Functions
	ViewportGL ()=default
	ViewportGL (const ViewportGL &)
	Copy operators do nothing, not to share GL data.
ViewportGL &	operator= (const ViewportGL &)
	ViewportGL (ViewportGL &&other) noexcept
ViewportGL &	operator= (ViewportGL &&) noexcept
	~ViewportGL ()
void	init ()
	Initialize all GL buffers and arrays.
void	free ()
	Free all GL data.
void	drawBorder (const Box2f &rect, const Color &color) const
	Binds and draws viewport border.
void	fillViewport (const Box2f &rect, const Color &color) const
	Fills viewport with given color (clear frame buffer)
bool	checkInit () const
	Check that members have been initialized.
PickResults	pickObjects (const PickParameters &params, const std::vector< Vector2i > &picks) const
	Find picked object, face id and z coordinate, of objects given in parameters (works for vector of picks)
std::vector< unsigned >	findUniqueObjectsInRect (const PickParameters &params, const Box2i &rect, int maxRenderResolutionSide) const
ScaledPickRes	pickObjectsInRect (const PickParameters &params, const Box2i &rect, int maxRenderResolutionSide) const
