Detailed Description

Draw an image with glDrawPixels() (write to frame buffer) 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 data
        Display::ImageDrawPixels disp;

        disp.update(image, 100, 100);
        disp.display();

Texture are not used, there is some performance issue when the texture needs to be update very fast (eg. playing a movie)

const

Draw the image with glDrawPixels if you need to position the image somewhere else use glRaster(x,y) instead of glTranslate, also glScale cannot be used
