Jonathan Gordon 2c71aa9feb 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.

images Resize some images that looked smaller or bigger than their 'relatives' in the html manual. Turned out that these had a different resolution (twice resp. half the size), probably taken with a different zoom level. 2009-02-12 11:02:26 +00:00
