Change log:

• Added magical vortex effect to highlight portals and collectable spells.

• Tree colors are now selected from the world palette.

• Edited most world palettes, you'll see more interesting colors now.

• Adjusted mana and portal effects a bit while improving trail effects.

• Fully transparent foliage is not rendered anymore.

• Fixed wrong color clamping for bright land colors.

• Fixed palette parsing bug which caused the grass to be gray.

I also researched new method for object shadows for some time, but its quality and performance isn’t good enough yet to release it.
