changed picking shaders to work with shaderGenerator

Shaders/Picking/pick_face.glsl

 // returns picking ids of faces in a n-poly mesh
 
-#version 150
-
 #include "colortranslator.glsl"
 
 uniform int pickFaceOffset;
 uniform isamplerBuffer triToFaceMap; // maps: triangle id in draw buffer -> face id in input buffer
 
-out vec4 outPickID;
-
 void main()
 {
   int faceID = texelFetch(triToFaceMap, gl_PrimitiveID).x;
 //  faceID = gl_PrimitiveID; // debug mode: skip reading from texture-buffer
   int pickID = pickFaceOffset + faceID;
-  outPickID = IntToColor(pickID);
+  outFragment = IntToColor(pickID);
 }

Shaders/Picking/pick_vertices_fs.glsl

 // returns picking ids of vertices
 
-#version 150
-
 in vec4 vertexPickID;
 out vec4 outPickID;
 

Shaders/Picking/pick_vertices_fs2.glsl

 // returns picking ids of vertices
 
-#version 150
-
 #include "colortranslator.glsl"
 
 uniform int pickVertexOffset;

Shaders/Picking/pick_vertices_vs.glsl

 // returns picking ids of vertices
 
-#version 150
-
 #include "colortranslator.glsl"
 
 uniform mat4 mWVP;

Shaders/Picking/single_color_fs.glsl

 // picking - all fragments have the same pick id
 
-#version 150
-
 uniform vec4 color;
 
 out vec4 outColor;

Shaders/Picking/vertex.glsl

-#version 150
-
 uniform mat4 mWVP;
 
-in vec4 inPosition;
-
 void main()
 {
   gl_Position = mWVP * vec4(inPosition.xyz, 1);
