Issue Type: DEFECT
Summary: Small fonts can crash Open Office on tightly packed

Product: Writer
Version: 4.1.1
Hardware: PC
OS: Windows 10
Status: UNCONFIRMED
Severity: Minor
Priority: P5 (lowest)

Open Office Build Info:
AOO411m6(Build:9775) - Rev. 1617669

When the provided sample file(big.txt) is copied and pasted into open office,
and then manipulated so that it's at the smallest possible font, with no new
lines, open office quickly begins to use more and more memory, and then
crashes.
To reproduce:
1. Download the text file, copy, and paste into a blank OO document.
2. use ctrl+a to select the entire document.
3. set the font size to 2
4. go to edit > Find and Replace
5. enable regexes, and replaces all instances of \n with a space
6. When the replacement is completed, attempt to scroll and select text.
The program should hang at this point, and you can watch the memory usage begin
climbing. On my system, it went from 100MB to 1.3GB before crashing.
I suspect it has to do with the size of the text buffer that has to be loaded
to be able to scroll smoothly.
