Hi All,

More workarounds for printing controls under Carbon.

The TCluster class has been re-written to use the standard toolbox
control; GROUP BOX (CDEF 10). This change was necessary to get the
control to draw to a gworld when printing. The TPrimaryCluster::Draw
method creates a gworld and then calls the DrawThemePrimaryGroup
function to draw the control to the gworld. The gworld is then copied to
the printing port.

The TSecondaryCluster::Draw method creates a gworld and then calls the
DrawThemeSecondaryGroup function to draw the control to the gworld.

The Change Log for all file changes are include below:
