I guess your document has the text in it justified? In non-justified text
we only have 1 run per line if the formatting is consisten across the
line; in justified text we have two runs per word. I think it should be
straight forward to improve the hanling of justified text so that in the
TextRun we would keep a vector of pair of numbers {offset,length}
which would indicate where in the run chunks of spaces start and
how long they are, and we could draw then our run in segments,
advancing the drawing point over the spaces. This would save us lot
of memory and processing time for justified text, costing only 4 extra
bytes per textrun in non-justified paragraph.
I am going to look into this particular issue sometime this week.
