Evas textblock: Speed up rendering. Find the start paragraph for all.
Until now all the format/text drawing loops went through all the paragraphs skipping all the ones that are outside the clipping/object zone. This changeset find the first paragraph to be renedred first so we don't walk all the paragraphs for nothing. This speeds up rendering of the ends of very big textblocks in a very noticable manner.
