Version 2.16 Patchlevel 7 Added Features/Bug Fixes

1. Fix bugs with sqrt() domain error. This happens with very very large page in tiled page mode. Thanks to Nobuyuki Miyajima <miyajima@kazusa.or.jp> for pointing out the problem. However, there will still be a limitation since 16-bit integers are used to represent coordinates (the XPoint structure is used).

2. Make the -DNO_STRSTR compile option work again. Also, reverse the left and right mouse button action on the zoom button to match what's in the Status Window. Thanks to Ralphe Neill <ran@rdt.monash.edu.au> for pointing out the problems.

3. Be able to launch an external viewer for an URL that ends with the '/' character. Thanks to Francis Ngoh <fngoh@asic.sc.ti.com> for pointing out the problem.

4. Allow Tgif*PrintCommand to use a '%s' substring to that a font can be downloaded to the printer. Please see the man pages for details. Also supports a -print_cmd command line option. Thanks to Kyle Bateman <kyle@actarg.com> for pointing out the problem.
