Subject: Fix 2037732: The warp layer is using a rough way of calculating how much context... 
X-Git-Url: https://git.pterodactylus.net/?a=commitdiff_plain;h=6efbfa12668470ae552d366baf539f5be142a002;p=synfig.git

Fix 2037732: The warp layer is using a rough way of calculating how much context needs rendering.  Any parts it misses are rendered pixel-by-pixel using get_color().  Layer_Duplicate::get_color() wasn't implemented, and so the duplicated layers weren't being rendered.  Now it is.  The warp layer still needs fixing.
