For use like pcolor but with c as a true color matrix (uses texturemap for speed)...

H=tcolor(x,y,c[,method])

valid methods are: 'corners','normal','triangles'

The normal method is texture mapping unto the plane given by x and y (which may be distorted arbitrarily)

The 'corners' method is the fastest way to draw. However it requires that the area is non-distorted... E.g. that the box defined by the corners defines the area.

The slowest method is 'triangles'... (sort of like pcolor). But shading interp works with it.

c=imread('C:\Projects\My Pictures\peppermint_girl.jpg');
[x,y] = meshgrid(1:size(im,2),1:size(im,1));
x=x+y/10; %skew the image
H=tcolor(x,y,c,'corners')
