0024310: TKOpenGl - GLSL compatibility issues

Browse Source 
Lights defintion clean up:
- remove duplicated enumeration TLightType (equals to Visual3d_TypeOfLightSource)
- remove unused fields from Graphic3d_CLight
- OpenGl_Light, reuse Graphic3d_CLight definition

Phong GLSL program:
- move out cumulative ambient light intencity from limited list of lights
- compatibility issues, replace array of structures (light sources, materials, clipping planes) with arrays of primitive types

New Draw Harness command vlight to alter light sources definition.

OpenGl_ShaderProgram::Initialize() - add missing Linker log

FUNCTION :
----------
File Visual3d_Light :
Declaration of variables specific to light sources
NOTES:
----------
A light source is defined by :
- type
- color
- reduction factors ( for positional and spot only )
- its angle ( for spot only )
- its concentration ( for spot only )
- its direction ( directional and spot only )
- its position ( positional and spot only )
It is active in a view, in the associated context.
ATTENTION:
----------
- AngleCone is given in radian [Pex] while OpenGl works in
degreees. The limits for Pex are [0,PI] while for OpenGl this is [0,90].
- Two reduction factors are used with Pex while OpenGl uses three.
- The ereduction factors have range [0.0,1.0] for Pex and
for OpenGl the range is [0.0,n]
- The concentration varies from [0.,1.0] for Pex to [0,128] for OpenGl.
