That's all the graphical assets we have in our game. Now, we already talked about how textures need to have power-of-two widths and heights. Our background image and all the help screens have a size of 320x480 pixels. We'll store those in 512x512-pixel images so we can load them as textures. That's already six textures.
Do we create separate textures for all the other images as well? No. We create a single texture atlas. It turns out that everything else fits nicely in a single 512x512 pixel atlas, which we can load as a single texture—something that will make the GPU really happy, since we only need to bind one texture for all game elements, except the background and help screen images. Figure 9-15 shows the atlas.
