- When drawing is not clipped to the top layers, drawing should not happen automatically on all existing layers. Instead each layer's flags dictate whether drawing should happen on layers beneath, starting with the top layer. - upon restore, the same mechanism is taken. Only blit a layer into the layer beneath if it was drawn into using the logic above. Also fixed: - saveLayer() does not, in fact, always save matrix and clip info. The flag dictate this, the same way it does in save() - drawing code didn't properly detect the case of drawing into layers if a save() was called after saveLayer(). Now the code only looks at the layer list which provide all the needed info (flags mostly), and doesn't rely on mLocalLayer (which is used during restore only now). - Properly handle HAS_ALPHA_LAYER_SAVE_FLAG (or lack thereof) when creating the BufferedImage for the layer.
