good idea :D

[SushiTee]

about what the map render should be able to do if we dont just upload a screenshot:

• flipping and rotating tiles
• color overlay above tile layers (also means u can make layers transparent)
• rendering quads acording to the 4 edges with and without textures (transforming textures)
• coloring the 4 edges which includes fading the colors above the texture like tw does

some examples:
image1
image2
image3
