There is currently no equivalent of java.awt.image.BufferedImage.getRGB() in TextureData, there are no methods to get and set the color of a pixel whereas our API is more and more used as a more cross-platform replacement of AWT. For example, some developers would like to compare the contents of several images in their unit tests. I modify a texture at runtime by using some data on the CPU.
