***Description***
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:

%|command|param1|param2|param3|param4|%
&|clearbuffer|red|green|blue|alpha|&
&|drawline|start_vertex|end_vertex|||&
&|drawtriangle|vertex1|vertex2|vertex3||&
&|filltriangle|vertex1|vertex2|vertex3||&
