On the X11/MSWindows platforms, this requires external installation of the GLEW library. This fixes STR#3198 and STR#3257. Added two new examples programs. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@10876 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

\brief FLTK standard box types
|
|
|
|
This enum defines the standard box types included with FLTK.
|
|
|
|
FL_NO_BOX means nothing is drawn at all, so whatever is already
|
|
on the screen remains. The FL_..._FRAME types only draw their edges,
|
|
leaving the interior unchanged. The blue color in Figure 1
|
|
is the area that is not drawn by the frame types.

Color indices occupy the lower 8 bits of the value, while
