[aprssig] Tickets CAD and Graphics

Folks, graphics are used in a couple of spots where it's useful, notably 
the new tracks-altitude and Incident Reports, the latter showing the 
distribution by incident severity, city, and type (as pie charts.)

If you don't see these graphics, it's probably because yr PHP options 
aren't set.  (You can confirm this by a look at yr phpinfo page; if set 
correctly, you'll see a GD heading almost halfway down the page.  If 
not, proceed as follows.)

Correcting that is straightforward.  Find your php.ini file, and there 
look for the line that refers to extension=php_gd2 something.  (It will 
vary by OS; in win32 environments it's "extension=php_gd2.dll")

Whatever it is, 'un-comment' that line by removing the semi-colon at its 
left end and saving the changed file.

A peculiarity for WAMP users: two copies of the php.ini file exist, one 
in the Apache directory and one in the php directory.  The 
'un-commenting' seems to be needed for both.

You'll need to re-start yr web server for that to take effect, so 
re-booting yr system is prbly the least involved way of doing that.
