Live Shader Editor

==================

This provides a live editor for vertex and fragment editors.

You should see a window with two editable panes on the left

and a large kivy logo on the right.The top pane is the

Vertex shader and the bottom is the Fragment shader. The file shadereditor.kv

describes the interface.

On each keystroke to either shader, declarations are added and the shaders

are compiled. If there are no errors, the screen is updated. Otherwise,

the error is visible as logging message in your terminal.
