Detailed Description

In order to prevent excessive duplication of GDI resources (creating HFONTs for identical LOGFONTs), manage a table of refcounted CP_FontRecords (which contain a LOGFONT and HFONT). Instead of CP_Font creating a font, it calls CP_FontRecord::LookupFont and if the identical font has already been created, it will use the existing one. HFONT disposal happens at the right time as long as the CP_Font unselects the HFONT when it's finished using it.
