Message #03198
[Merge] lp:~widelands-dev/widelands/texture_atlas into lp:widelands
SirVer has proposed merging lp:~widelands-dev/widelands/texture_atlas into lp:widelands.
Requested reviews:
Widelands Developers (widelands-dev)
For more details, see:
https://code.launchpad.net/~widelands-dev/widelands/texture_atlas/+merge/243119
Suggested commit message:
- Adds a TextureAtlas bin packer and packs the terrain textures into one OpenGL texture. This needed more features in class Texture: a Texture can now also be a rectangle in another, bigger texture.
- Changed the terrain rendering to use this new texture. This is the fastest terrain rendering we ever had.
- class Graphic no longer owns map textures and animates them. They are owned by their TerrainDescription class and animation is done through handing gametime through to this class. This cleaned it up quite a bit.

Your team Widelands Developers is requested to review the proposed merge of lp:~widelands-dev/widelands/texture_atlas into lp:widelands.
