rename

[mayakraft]

lines are represented by a point and a vector. for consistency across all transforms, vectors and rays and shapes, and because it is more properly descriptive: rename "point" to "origin"

[mayakraft]

"points" is the name of an array of points that define a boundary to a polygon
"point" is a point in 2d space (or any d), used in calculation for distances etc..

everywhere else, "origin" is used to mark the location of a line, ray, circle, rect, center of rotation transform, etc...
