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. Change-Id: I741498e2af6d4f2d78932cabe8942317893e7cfc
