Structures Graphic3d_CView, Graphic3d_CStructure, Graphic3d_CGroup become classes and their definitions moved from InterfaceGraphic to Graphic3d. Introduced new class OpenGl_Texture as replacement for OpenGl_ResourceTexture class and static functions in OpenGl_TextureBox. Graphic3d_TextureRoot now no more communicate within Graphic3d_GraphicalDriver. Instead class returns image through GetImage() method. OpenGl_AspectFace - avoid possible NULL-dereference OpenGl_Texture::Init() - check gluBuild2DMipmaps() return value OpenGl_Texture - check GL_BGRA_EXT for compatibility OpenGl_Texture - scale NPOT image when required Added more description to Graphic3d_TextureRoot class OpenGl_Texture - added missing break statement for ImgBGR32 case OpenGl_Workspace::setTextureParams() - fixed local variable aFilterMin overrides visibility of early declared variable OpenGl_Workspace::DisableTexture() - reset texture matrix FTGL do not reset texture matrix and corrupt text could be rendered if custom texture has not identity texture matrix.
