VG3_get_xy_direction_from_angle()

Return x-/y-directions of a given angle.
SYNTAX
int VG3_get_xy_direction_from_angle(int angle, int *xdelta, int *ydelta)

FUNCTION PARAMETERS
angle Angle in degrees
xdelta For returning x-direction in 1/100 pixels
ydelta For returning y-direction in 1/100 pixels

RETURN VALUE
Returns the same angle, but corrected from 0 to 359.

DESCRIPTION
Return x-/y-directions (based on 1 pixel) of a given angle. E.g. for an angle = 45 degrees, it sets x-direction = 71 and y-direction = -71, which means 0.71 pixels in x-direction an -0.71 pixels in y-direction.
