c1045881dd if we're not going to notify parents of bbox changes while an item is hidden, we need to remind it when the item is hidden or shown 2014-06-18 21:02:30 -04:00

93bc93b6f6 a set of 3 fixes that cure Canvas::Text leaving dirty pixels when being dragged. or might not - testing is non-deterministic, which is alarming 2014-06-17 11:34:54 -04:00

590882f3c8 change Canvas heirarchy and constructors
Items no longer need a parent group (they require a Canvas pointer instead), so all constructors have been rationalized
and have two variants, one with a parent and one with a canvas.

All Items now inherit from Fill and Outline, to banish diagonal inheritance and virtual base classes and all that.

There were zero changes to the Ardour GUI arising from these changes.

7a05dde39d Use a dumb cache for waveview ImageSurfaces. This halves the size of the
previous one, but usually ends up using three of them at the current
CACHE_HIGH_WATER setting.
Should result in a smaller memory footprint for sessions with
multiple copies of nearby audio segments (electronic style).
The downside is the larger memory footprint for linear recording
sessions if CACHE_HIGH_WATER > 1 (1 giving a max of two
half - sized cache entries per audio stream).

792fe016e7 clip rendering of ScrollGroup to just the part of the canvas covered by the scroll group.
This stops tracks from appearing to scroll up under the rulers, among other things.

073df89c4d use window-based coordinates when picking current item so that we get per-item (per-scroll-group,really) computation of position and coverage. 2014-06-03 16:12:00 -04:00
54a56cd3c6 various changes to get independent scrolling to work better in canvas. mostly tweaks relating to how scroll offsets are used during rendering.
Event handling offsets still require work.

6019f06bdf different approach to independent scrolling, involving ArdourCanvas::ScrollGroup
The idea now is that a scroll group item can be added to the canvas which will causes its children to scroll in either or both
directions (horizontal or vertical). There are few complications: the position() of the ScrollGroup is ambiguous depending
on whether you want it with scroll taken into account or not, so Item::canvas_position() was added, which defaults to
the same value as Item::position() but is overridden by ScrollGroup to return the position independent of scrolling. This
method is used when translating between item/canvas/window coordinate systems.

Note that the basic idea is that we MOVE the scroll group when a scroll happens. This mirrors what happens in the GnomeCanvas,
where Nick Mainsbridge came up with a great idea that allowed unification of the time bar and track canvases.

97109672c7 initial redesign of canvas scrolling to facilitate independent x- and y-axis scrolling of specific groups within the canvas.
This commit should cause no change in behaviour, but contains all the code and changes necessary
