#605 map rotation
This patch provides the interface to rotate the map, but does not implement it. The controls allows for cc/cw 30/90 rotation, and also provides setting the rotation directly to any multiple of 30. Instead of rotating the map, a g_warning is thrown stating the current direction, which will be changed when the implementation is written.
There are two ways I can see this implemented.
First: Rotate the hexes from the .png files.
Second: Make additional .png files that is rotated 30 degrees. and use the different .png file for the different hex orientation.
Provides the interface to rotate the map.
In the theme definition file, each theme could be marked:
- Tile: the provided image can be tiled to fit in the hex shape, the pattern does not need to be rotated
- Scale: the provided image must be scaled and rotated to fix (because it has a hex shape)
- NEW: Rotate: the provided image is a square (at least a circle), and can be scaled to fix the hex shape. When a rotation is needed, the hex shape can applied without rotating the image.
I would prefer to have a simple UI: 0 and 90 degrees will be the most common choice.
