New Revision: 6750
Log:
removed dead html anchors from, and improved layout of, fluid.dox
added a lot of \par commands to get indented paragraphs for the
reference section, basically because the paragraph titles stand
out more than the \subsection titles. Do we need to rethink this?

\par Notes for All Image Types
+\par
FLUID runs using the default visual of your X server. This
may be 8 bits, which will give you dithered images. You may get
better results in your actual program by adding the code
"Fl::visual(FL_RGB)" to your code right before the
first window is displayed.
+\par
All widgets with the same image on them share the same code
and source X pixmap. Thus once you have put an image on a
widget, it is nearly free to put the same image on many other
widgets.
+\par
If you edit an image at the same time you are using it in FLUID,
the only way to convince FLUID to read the image file again is to
remove the image from all widgets that are using it or re-load the
<tt>.fl</tt> file.
+\par
Don't rely on how FLTK crops images that are outside the
widget, as this may change in future versions! The cropping of
inside labels will probably be unchanged.
+\par
To more accurately place images, make a new "box"
widget and put the image in that as the label.
\par XBM (X Bitmap) Files
+\par
FLUID reads X bitmap files which use C source code to define
a bitmap. Sometimes they are stored with the ".h" or
".bm" extension rather than the standard
".xbm" extension.
+\par
FLUID writes code to construct an Fl_Bitmap image and use it
to label the widget. The '1' bits in the bitmap are drawn using
the label color of the widget. You can change this color in the
FLUID widget attributes panel. The '0' bits are transparent.
+\par
The program "bitmap" on the X distribution does an
adequate job of editing bitmaps.
\par XPM (X Pixmap) Files
+\par
FLUID reads X pixmap files as used by the \p libxpm

filenames usually have the ".xpm" extension.
+\par
FLUID writes code to construct an Fl_Pixmap image and use it
to label the widget. The label color of the widget is ignored,
even for 2-color images that could be a bitmap. XPM files can
mark a single color as being transparent, and FLTK uses this
information to generate a transparency mask for the image.
