LOK: tilebench improvements
* Arguments for max number of parts and tiles to render (optional).
+ Automatic estimation of maximum tiles to render based on max parts
for Writer docs, since there is only 1 part, this caps the number
of pages to render, similar to other doc types.
* Fixed rendering of Writer documents over and over (as many times as pages).
+ Writer has a single part, unlike other doc types.
+ No point in rendering the whole document in writer to a single tile,
since that's completely unrealistic and impractical (it takes
forever for large docs and artificially spikes the memory).
* Rendering starts at the current part and not the first.
+ This gives the spreadsheet of interest priority (if saved as visible).
* The tile size is now more realistic as we use the same dimensions
as the Online client does.
* When rendering tiles at scale, we use the same dimensions as the
Online client rather than splitting the width by 4, for realism.
* Rendering of tiles is done rows-first, rather than columns-first,
which is similar to what the Online client does, which is more
cache friendly, therefore more realistic.
* Enabled compiling of tilebench when GTK3 is disabled, which
was erroneous, since tilebench doesn't have any dependency on GTK.
+ Now it's possible to compile with local Cairo/Pixman libs.
