fix rect redraw problems caused by intersection requiring the usual 0.5 expansion (though consider a more general fix for this at teh group level)

basically operational switch to canvas drawing coordinates, although text and waves don't work, and redraw areas are too small

fix incorrect 3rd arg to AudioRegion::read_peaks() - was passing end, not cnt. Fixes waveforms at high zoom

no create cached waveview images that span from render-start to cache-start, but always clamp the end to render-end, to avoid creating over-sized images

display waveform polarity correctly
* cairo's Y axis points downward -> invert phase display
* fix logarithmic view for value.max < 0

make waveform gradient depth continuously variable. color probably needs adjusting as do color stops to get a pleasing effect at most settings

virtual Fill:: and Outline:: methods so that Canvas::Items that cache image renderings of themselves can invalidate those caches when colors etc. change; add Item::{begin,end}_visual_change() so that we can notify the canvas more efficiently when *only* visual properties have changed and not the bounding box (probably needs to be used more widely)

remove all XML related API from canvas. it may have been useful during development, but it is just a distraction - we will NEVER be saving or restoring canvas state via XML or any kind of serialized state
