Detailed Description

Configuration for the background-image (Graphics 2) layer.

Graphics 2 is the lower layer in the GLCDC blender; Graphics 1 (the UI overlay configured by ra8_glcdc_init) is composited over the top of it. Layer 2 has its own framebuffer base, format, line stride, on-panel position, on-panel size, and a constant alpha that gates alpha-blending of the lower layer.
