0022582: Visualization - provide an API for dumping a sub-region of the viewport

Browse Source 
Graphic3d_Camera definition has been exended by optional Tile property (Graphic3d_CameraTile structure).
V3d_View::ToPixMap() now performs tiled dump when image size exceeds hardware limits.

OpenGl_View::Redraw() - fixed dump of immediate Z layers in no stereo and no MSAA case.

OpenGl_Context now tracks viewport values.
Draw Harness command vdump has been extended with new argument -tileSize.
