LoadFontTexture caches all of the glyph pixel data in an OpenGL texture for a given font at a given size.

NewBufferObject returns a new buffer object.

NewCubeMap creates a CubeMap object that wraps the OpenGL texture functions.

NewFrameBuffer creates an FBO of the specified size that renders to a texture.

NewProgram compiles a vertex and fragment shader, attaches them to a new shader program and returns its ID.

NewShader attempts to compile the given shader source code as a shader of type shaderType (e.g.

NewTexture creates a Texture object that wraps the OpenGL texture functions.

NewTextureFromFile creates a new Texture, loading data from fileName with the assumption that it is an image that can be converted to RGBA (alpha is black for jpegs).

NewVAO creates the structure necessary for efficiently rendering shapes in OpenGL.

AlignAbove puts the top side at the y coordinate.
