Added GLSL shader for windows  !!!! GLSL shaders are NOT the same as GLSL ES shaders !!!!

Moved shaders to subfolders
Using glen's filepath system to load shaders file paths

Changed testscene and testscene2 draws
Now android and windows use the same opengl drawing code to draw png's
Matrix implementation needed inside the shaders for correc taspect ratio

Works in VS and Eclipse
