First commit.
Fixed some spelling mistakes and hopefully made the build instructions to make a bit more sense.
The Linux-specific libraries are now only linked on Linux.
build.sh now builds a 32-bit build on 32-bit systems and a 64-bit one on 64-bit systems by default.
operator!= in the vector2 class now returns the opposite of operator==.
Added a vector3 class.
sample-multiple-windows places the windows next to each other now - not above each other like before.
Windows now have OpenGL contexts.
Implemented a color struct.
Functions for setting the background color and drawing in the window.
Added sample-opengl for testing OpenGL contexts.
The required dependencies can now automatically be installed with build/dependencies.sh.
Added a section about Feather to readme.markdown.
Initializing OpenGL extensions with GLEW.
Changed sample-opengl to use non-deprecated OpenGL.
dependencies.sh now installs g++-4.7 if needed.
Made the build instructions a bit clearer in readme.markdown.
dependencies.sh shouldn't prompt for confirmation anymore while installing g++.
Implemented a "drawable" class that can be used for drawing to windows.
Added a build/generate.bat to generate project files for Windows.
