Description of problem:
Any text document viewer should be capable do (optional) case-sensitive search,
but it seems as Atril lacks this functionality, and searching is implemented somehow badly. Concretely:

• button/checkbox for specifying case-significant/caseless searching missing (tested on PDF and DjVu documents)
• entering text with upper-case character in "Find:" results to not finding
  text in document, although this text is there! (tested with DjVu document)

Version-Release number of selected component (if applicable):
mate-document-viewer-1.6.1-5.fc19

Expected results:
Searching function should be able do at least optional case-sensitive/nonsensitive search, eventualy more advanced search options as searching text on word boundary, searching by regexp etc.

Broken searching in DJVU documents should be corrected (e.g. djview4 DjVu viewer search docoments without problems)

Case sensitive check box was available in the previous evince code, but not shown and not working.
I fixed it, but now case sensitive search need to be fixed in the varios backends.

For example, case sensitive search in poppler is available only from 0.22 version:
