Added methods to specify Image_PixMap as texture source to AIS_TexturedShape and Graphic3d_TextureRoot. Modified internal class MeshVS_ImageTexture2D, originally used for the purpose of sourcing texture as Image_PixMap. AIS_TexturedShape class: - Get rid from cdl declaration. - Remove unused and uninitialized field myDeflection / method Deflection(). - Improve class documentation. - Use Graphic3d_NOT_2D_UNKNOWN instead of -1. - Use myIsCustomOrigin and myToScale flags to use/ignore custom values.
