civicrm.css refers to non-existing png files

I fixed item 1 below, but need help on the following issues:

1. Currently, many spots in civicrm.css reference this path:
../packages/jquery/jquery-ui-1.8.16/css/custom-theme/images
For example line 2760 ->
background: #484e4c url("../packages/jquery/jquery-ui-1.8.16/css/custom-theme/images/ui-bg_flat_40_70716b_40x100.png") 50% 50% repeat-x;

• • • • • HOWEVER, I do NOT see custom-theme directory in that location in svn, only smoothness. Not sure what to do with these - did we miss picking up a directory for jquery ui 1.8.16 ???

2. I can't see where this class is used on the code, and I don't understand why it declares a background (quiz.png) AND a background-image (ui-icons ....)??

div.statusicon {
background : transparent url(../i/quiz.png) no-repeat;
display : inline-block;
cursor : pointer;
background-position:-48px -144px;
background-image:url(../packages/jquery/themes/smoothness/images/ui-icons_222222_256x240.png);
background-color:#CCC;
width:16px;
height:16px;
overflow:hidden;
text-indent: -10000px;
}

— Original Post —
in the /i/icons folder, the following files are present:

jquery-ui-2786C2.png jquery-ui-52534D.png jquery-ui-91CE00.png jquery-ui-FFFFFF.png
jquery-ui-3E3E3E.png jquery-ui-8A1F11.png jquery-ui-F5F6F1.png jquery-ui-b0d730.png

Only one of them has color in its name made of small letters, all other have large letters in color code.

Error is in civicrm.css:
civicrm.css: background-image:url(../i/icons/jquery-ui-3e3e3e.png);

There are other places where the filename is specified correctly:

civicrm.css:#crm-container .ac_results li a:hover .icon

{ background-image:url(../i/icons/jquery-ui-3E3E3E.png); }

Also civicrm.css tries to reference jquery-ui-1.8.5, while jquery-ui-1.8.11 is provided with the installation.

civicrm.css: background-image:url("../packages/jquery/jquery-ui-1.8.5/css/custom-theme/images/ui-icons_8d2c27_256x240.png")!important;

There is no jquery/themes folder now, while civicrm.css refers to it:
civicrm.css: background-image:url(../packages/jquery/themes/smoothness/images/ui-icons_222222_256x240.png);
