From 2c71aa9feb0268da7d993feddbbe4db591fcd3ba Mon Sep 17 00:00:00 2001 From: Jonathan Gordon Date: Tue, 28 Feb 2012 22:26:32 +1100 Subject: lcd/skin_engine: Add the ability to draw onto the backdrop layer The framebuffer the lcd driver uses can now be changed on the fly which means that regular lcd_* drawing functions can draw onto the "backdrop" buffer. The skin engine can use this to create layered effects. Add the tag %VB to a viewport to draw that viewport onto the backdrop layer. If you want to draw an image onto the backdrop framebuffer use %x(backdrop filename) instead of %X() inside a viewport with %VB.
