command: extend osd-overlay command with bounds reporting
This is more or less a minimal hack to make _some_ text measurement functionality available to scripts. Since libass does not support such a thing, this simply uses the bounding box of the rendered text. This is far from ideal. Problems include: - using a bitmap bounding box - additional memory waste and/or flushing caches - dependency on window size - odd small deviations with different window sizes (run osd-test.lua and resize the window after each timer update; the bounding boxes aren't adjusted in an overly useful way) - inability to query the size _after_ actual rendering But I guess it's a start. Since I'm aware that it's crap, add a threat to the manpage that this may be changed/removed again. For now, I'm interested whether anyone will have use for it in its current form, as it's an often requested feature.
