BumpMap Material (TGorillaBumpMapMaterialSource)
The TGorillaBumpMapMaterialSource (TGorillaBumpMapMaterial) is inherited from the TGorillaNormalMapMaterialSource, supports multiple light sources and extends normal-mapping functionality by a specular texture map for better specular color results by: GORILLA_GLSL_DEFINE_BUMP
Hint: Due to historical development of Gorilla3D this is called BumpMap-Material, even if this terminologically not fully correct.
By this material a new SpecularMap texture property is provided.
