XV modification notes

The following is my notes on posible modifications of the XV program to
allow improved usage of the program.

I do suggest you keep a copy of the original unmodified XV, particularly if
you decied to modify thumbnail size!

The Source for XV I used was the last  XV 3.10a release
   http://www.trilon.com/xv/downloads.html#src-distrib
Then patched with the latest   Greg's XV Jumbo Patch
   http://www.sonic.net/~roelofs/greg_xv.html

I then patched as per below, and modify the 'VSRSTR' in "xv.h"

-------------------------------------------------------------------------------
Max Number and size of Schnauzer.

I found that a maximum of 4 browser windows were not enough...

In "xv.h" change the the following defines...
  #define MAXNAMES 4096              /* max # of files in ctrlW list */
  #define MAXBRWIN   4               /* max # of vis browser windows */
to
  #define MAXNAMES 10240             /* max # of files in ctrlW list */
  #define MAXBRWIN  16               /* max # of vis browser windows */

-------------------------------------------------------------------------------
Increase XV thumbnail size (caution)

On a larger display, I found the  80x60 thumbnail size is a little small.

Warning a unmodified xv will think larger thumbnails as bogus and ignore them.
It does NOT however over-write them unless you "update" or re-"generate"
specific icons.  I suggest you do not copy larger .xvpic thumbs to machines
where a different XV might be running.

Alturnativally prehaps you can rename the "thumbnail" directory from ".xvpics"
to ".xvpics-120" (set in "xv.h") so that both sets can co-exist. I did not
bother.

Also I suggest you keep the 4x3 aspect ration of the thumbnails

In "xvbrowse.c" modify..
  #define ISIZE_WIDE   80    /* maximum size of an icon */
  #define ISIZE_HIGH   60
to
  #define ISIZE_WIDE   100    /* maximum size of an icon */
  #define ISIZE_HIGH   75
or even larger at
  #define ISIZE_WIDE   120    /* maximum size of an icon -- my selection */
  #define ISIZE_HIGH   90

You may also like to remove some of the extra width space around icons...
  #define ISPACE_WIDE (ISIZE_WIDE+16)   /* icon spacing */
to
  #define ISPACE_WIDE (ISIZE_WIDE+4)   /* icon spacing */

To do all this properly with window size adjustments needed,
this context diff patch will do the job for you...
