writes the coordinates for points on a 2D circle into an array

Remarks:

TODO : optimize me using sin,cos tables ?

Parameters:

	a	The array to write to, must hold at least blocks * components
	blocks	number of blocks(e.g. vectors) in the array
	components	each "block" consists of this many Reals, only the first 2 receive circle coords
	startang	for partial circle, 0.0 results in the first point being on (0,1),...,(1,0)... (clockwise)
	endang	for partial circle
	setOtherComponentsToZero	initializes components after the second to zero

		size_t	startoff = 0,
		size_t	bufsize = 2,
		eInterpolationMode	mode = kInterpolate_Linear,
		size_t	stride = 0
	)			[static]

n float interpolation (vectors,colors,..)

Parameters:

	source	array with source values, must have at least space for "bufsize" Reals
	dest	result is written here, must have at least space for "num" Reals
	t	"time" for interpolation, [0.0;1.0]
	num	number of Reals to synchronously interpolate, e.g. 3 for 3dvectors x,y,z
	startoff	the offset (in Reals) of the first coordinate at t=0.0, the entries this one are also considered for quadric mode, if they are inside the buffer
	bufsize	the number of floats in the buffer
	mode	see eInterpolationMode

See also:

eInterpolationMode

Parameters:

stride

number of "unused" (e.g. not interpolated) Reals after a "num" block, useful if quaternions etc are in the same buffer, and are interpolated differently
