/**
 * This {@link de.lessvoid.nifty.render.batch.spi.BatchRenderBackend} implementation includes full support for multiple
 * texture atlases and non-atlas textures.
 *
 * LibGDX-specific implementation of the {@link de.lessvoid.nifty.render.batch.spi.BatchRenderBackend} interface. This
 * implementation will be the most backwards-compatible because it doesn't use any functions beyond
 * OpenGL / OpenGL ES 1.1. It is suitable for both mobile & desktop devices.
