Detailed Description

2D image viewer

Draw an image with 2D textures Currently support any native image type (ie. unsigned char, unsigned short, and others) use update and display when image is changed:

        unsigned char* image = new unsigned char [100*100]; // fill the data
        Display::Image disp;

        disp.update(image);
        disp.display();

If an image needs to be updated very fast (eg. playing a movie) transfers to the texture memory can become a bottleneck In this case, Display::ImageDrawPixels<T> might be more suitable as it directly writes the image in the frame buffer.

Todo:

Should be able to display any image size
