TclGles20 is a layer package, which makes some of the OpenGL es 2.0 commands available (callable) from Tcl.
A Vertex has the Tcl form ([list position color]):
[list [list x y z] [list r g b a]]
Position and color values are float values (colors between 0 .. 1).
Here is a list of the planned commands (all live in namespace ::gles20):
