How do you increase the resize border thickness in Xubuntu 12.04?

I found the only easy answer was to learn to use the alt-right button-drag thing. Which once you get used to it is pretty handy, and of course therefore is sorely lacking in windows. :-(

Here's an explanation of increasing the border size:

Summary:

XFCE theme files use a XPM3 file format. To change the Greybird Window borders, find the theme XFCE files under:

cd /usr/share/themes/Greybird/xfwm4/

Then, back up the files and try tweaking. Increase the width to 4px and add a one pixel dark border:

sudo vi bottom-active.xpm

/* XPM */
static char * left_active_xpm[] = {
"1 4 2 1",
"  c #cecece",
". c #7c7c7c",
" ",
" ",
" ",
"."};

sudo vi left-active.xpm

/* XPM */
static char * left_active_xpm[] = {
"4 1 2 1",
"  c #cecece",
". c #7c7c7c",
".   "};

sudo vi right-active.xpm

/* XPM */
static char * left_active_xpm[] = {
"4 1 2 1",
"  c #cecece",
". c #7c7c7c",
"   ."};

To trigger a refresh, you can use:
