0024181: Text to BRep functionality

Browse Source 
Introduce new class Font_BRepFont for conversion of font glyph in vector format into BRep representation.
New text2brep Draw Harness command.

bottle.tcl - draw text on the bottle side using new functionality.
ViewerTest - process Delete key in 3D-Viewer to delete selected presentations.
Font_FontMgr::FindFont - return correct font when font alias and not default aspect is requested.

bottle.tcl - use prism instead of pipe

TKViewerTest - add required FreeType dependency

verase - display the list of erase objects

TKViewerTest - add required FreeType dependency for projects generation
