0030497: [REGRESSION] Mesh - wrong Poly_Polygon3D within local selection of located shape

The previous code has a condition to avoid processing the same faces if the face has a location.
The similar condition should be applied during the edges processing.
If not doing this, in the previous implementation, IMeshData_Edge instances are created for all edges(even located), but edges of faces located are not filled with curves.
As a result we had wrong local selection of edges.

Limit addition of edges to data model by ones with unique TShape and location using edges map already available in BRepMesh_ShapeVisitor.

0029810: Visualization - Tool for debugging shaders

A new tool for debugging shaders has been introduced.
The new method OpenGl_ShaderProgram::UpdateDebugDump() allows dynamically
dumping/restoring certain shader program (vertex and fragment shaders) to/from external file.

The file name is generated from the program's name with suffix ".vs" or ".fs" for shader type.
The environment variable CSF_ShadersDirectoryDump specifies the folder for dumps.

If the file does not exist (first frame), then it is automatically saved.
When the file date/time is changed in comparison with recent cached date,
then the file will be automatically loaded from external file,
thus this file can be modified in any editor.

OpenGl_ShaderManager now generates a human-readable resource ids for standard GLSL programs.

Draw Harness command vshader has been extended with arguments -list,-dump and -reload
for debugging shaders within OpenGl_Context.
