GoPoints
A very simple Go library for creating shapes on a 2D plane out of points, using only the Go stdlib. Supports some basic functions like:
 storing points in a
Plane
structure  joining arbitrary points with lines (including diagonal)
 filling shapes with points
 flipping the whole plane or some points along the X or Y axis
 fetching all points from a plane
 fetching points from a plane based on the return value (boolean) of a given function (like a mathematical equation)
 TODO: Applying an arbitrary transformation based on a function to the points on the plane
Use cases
Can be used for any number of things, but my primary usecase is generating images made of 2D shapes, such as the example image generated with examples/CreatePngImage.go
