Options for texture wrapping

[sphereflow]

Hi, I have added support for texture wrapping and added examples in the gfx_graphics and opengl_graphics repositories.

1. Can I submit a pull request?
2. Should I name texture coordinates u v or s t like OpenGL does?
3. I have made changes to the following repositories:
   • https://github.com/PistonDevelopers/texture
   • https://github.com/PistonDevelopers/gfx_graphics
   • https://github.com/PistonDevelopers/gfx_texture
   • https://github.com/PistonDevelopers/opengl_graphics I am unsure which versions to bump, if any. Edit: Relevant pull requests:

     50

1. Yes!
2. I prefer u v.
3. Just make PRs, then I'll merge them and do the bumps (I use a tool called "Eco" for analyzing dependencies).

Thanks for the PRs!
