new image cache design for waveviews, with various fixes.
...
Rather than maintain a set of images in a cache, when we no longer have the required waveform data, create a new image that is appropriately centered and extends to roughly twice the screen width (or the limits of the region's source file(s), as necessary)

get wave drawing improved, but commit before i tear it all up and go back to a single cached image per waveview

inching pretty close to fully working waves now

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

don't invalidate image cache for every regionr esize, only region start changes

many pervasive changes primarily related to waveform drawing, particular content-dragging, colors, and more

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

* 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
