- add constants for each minimap color
- rename, reorganize and make static minimap functions
- main.c:draw_screen() calls draw_minimap() instead of render().
- clean code and norm
fix:
- fix texture for each direction (north texture is in north etc)
- fix mirror textures (the left of each texture is at its left)
- fix dimensions (walls are 1x1 for any window dimensions or FOV)
- optimize render()
dev:
- add testmaps/good_directions_test.cub
- add textures/test/*.xpm
