0028811: Visualization - merge texturing support into AIS_Shape class and get rid of AIS_TexturedShape

Browse Source 
AIS_Shape and AIS_ColoredShape now computes Shaded presentation
with UV coordinates if texture mapping is enabled in Drawer.

OpenGl_Context::SetTextureMatrix() - fixed inconsistent handling
of texture cooridnates translation vector.

vtexture command has been extended to handle new arguments:
* -trsfTrans, -trsfScale, -trsfAngle defining transformation matrix
* -setFilter, -setAnisoFilter to setup texture filtering
