Package organization

One package for each OpenGL version:

• gl21 package for OpenGL 2.1
• gl31 package for OpenGL 3.1 (without deprecaded functions)
• gl31d package for OpenGL 3.1 (with deprecated functions)
• ...

Group extensions by vendor:

• GL_NV_register_combiners, GL_NV_fence, GL_NV_vertex_program, GL_NV_???, ... -> nv package.

• GL_ATI_map_object_buffer, GL_ATI_vertex_attrib_array_object, GL_ATI_???, ... -> ati package.

• Same for GL_EXT_???, GL_ARB_???, ...

Planned usage:

// Import pure OpenGL 3.1 + all ATI and EXT extensions ...`
import (`
 "http://github.com/chsc/GoGL/gl31"`
 "http://github.com/chsc/GoGL/nv"  // Import all GL_NV_ extensions
 "http://github.com/chsc/GoGL/ati" // Imoort all GL_ATI_ extensions
 "http://github.com/chsc/GoGL/ext" // Imoort all GL_EXT_ extensions
)
...

// Init GL_EXT_framebuffer_multisample
if err := ext.InitFramebufferMultisample(); err != nil {
... // handle error
}

// Single context interface:

gl.Init()
gl.Clear(gl.COLOR_BUFFER_BIT)

// Multi context interface (future):

// make context 1 current
// ...
glctx1 := ext.LoadXYZExtensionByCurrentContext()

// make context 2 current
// ...
glctx2 := ext.LoadXYZExtensionByCurrentContext()

// do something with context 2:
glctx2.FooBar(...)
...

// make context 1 current
// ...
// do something with context 2:
glctx2.FooBar(...)
