When creating a presentation/drawing with Thai text using Impress or Draw and
export it to Flash, the text in flash document doesn't look right. On Windows,
the Thai clusters don't get shaped correctly according to normal Thai shaping
algorithm. The diacritics are also shifted to the left by about half of the
width of a Thai consonant. On Linux, they become garbages.

Test case:
1) Load the attached Impress document. It contains a line of Thai in the page
title and looks correct in Impress.
2) Load the PDF that was exported from Impress. It also looks correct.
3) Load the SWF flash file that was exported from Impress on Windows. It'll look
different from how it look in Impress and PDF. The clusters don't get shaped
(e.g. ญ +  ู must be ญู). And all diacritics are shifted to the left.

4) Load the attached Draw document. It contains a short line of Thai. It looks
correct in Draw.
5) Load the SWF flash file that was exported from Draw on Linux. After the
character with a diacritic, there's a garbage. The problem exporting to flash on
Linux seems to be different than on Windows. If there's any diacritic, it'll
become a garbage. I also test this with Impress.

I guess that this problem should happen to other CTL languages which need
shaping before display.
