Class SDLGfx

public class SDLGfx extends Object

Binding to the SDL_gfx library

Note: all ___Color routines expect the color to be in format 0xRRGGBBAA

Also note in the functions which take a list of points (ShortBuffer), the length is inferred from the size of the buffer, you do not have to specify it to the function, SDLGfx will take care of this for you. No checking is done to ensure vx.capacity() = vy[].capacity() so make sure they are the same length or the results could will most likely be a segfault.
