Detailed comparison with more options

Ok, here is a more detailed comparison with options separately
enabled/disabled. Caution: The screenshots incorrectly say "5.4.2.1", but
"5.4.1.2" is correct!
The results are as follows:

LibreOffice 5.4.1.2 (current release)
a) OpenGL off:
- Rendering is ugly and blurry (both UI and in-document)
- "Hardware acceleration" on/off has no effect
- "Anti-aliasing" on/off has no effect
b) OpenGL on:
- Rendering is slightly different (but still ugly and blurry)
- Horizontal ruler: Different rendering of vertical lines
- "Hardware acceleration" is disabled
- "Anti-aliasing" on/off has no effect

LibreOffice 5.3.1.2 (last known good)
a) OpenGL off:
- Rendering is crispy and sharp (both UI and in-document)
- "Hardware acceleration" on/off has no effect
- "Anti-aliasing" on/off has no effect
b) OpenGL on:
- Rendering is ugly and blurry as in 5.4.1.2 (no extra screenshots)

So the only way to get sharp rendering is to (1) use LO before 5.3.2 and (2)
disable OpenGL (which has always been ugly and blurry, as already said in my
previous comments).

However, I couldn't observe any specific differences caused by hardware
acceleration, anti-aliasing, or between UI and in-document content.
