update color.rs with new predefined color, color is now cloneable and update the example
Rects and Vertex are now cloneable too
vectors are now cloneables, update ContextSettings class, there is now an default static method and update the pong example.
Rename sfml module to respect more rust modules hierarchy.
Begin to refactor rsfml::sfTypes, internal style only, no change for the api.
continue to clean SfBool with SFTRUE and SFFALSE, internal only.
Add clone for Glyph, fix some coding style, clean some use.
add new constructors for vertex
add doc for Vertex's new constructors
clean more style
clean code, modify example on readme
replace uint in ContextSetting by u32
Implement traits (Ord, Eq, Mul, Div, Add, Sub) for somes structs
Update example to work, add method set_size2f on render_window and rectangle_shape,
implement toVec for vector2,
Replace all the resource management (@mut), by borrow pointer (&'self), resource don't need to be mutable when they are assigned to an other object
update Shader, take now Option<~str>, pass None if you don't use vertex or fragment shader
remove all mention of NULL in doc.
module reexport now them own submodules, example :
graphics module reexport RectangleShape, you can import RectangleShape by two way :
   - use rsfml::graphics::rectangle_shape::RectangleShape;
or
   - use rsfml::graphics::RectangleShape;
or you can import directly all the module :
   - use rsfml::graphics::*;
update mouse and window to try window reexport.
