If the fonts are mapped for some reason to X bitmap fonts,
the call to drawText() in the non-GUI thread will produce a crash.
Ensure that the rendering of the text is performed only if
the threaded font rendering is available - a rare event nowadays,
but still possible.
CCBUG: 248852
Adapted from the DVI plugin of KViewShell.
It can:
- load documents
- generate correctly the pixmaps for the images
- rotate the pages
- extract the text from the pages (thus search and text selection are possible)
- extract the URL hyperlinks from the documents
