3bd5b0eadf Add support for recursive dependency tracking across PropertyTracker instances 
By default PropertyTracker::evaluate() registers the currently
evaluating binding/tracker as a dependency. This should help with
repeaters and other scenarios where in the run-time we use property
trackers but want to track the overall "dirtyness" in the window with
regards to whether a redraw is needed or not.

The new evaluate_as_dependency_root() function allows skipping this
mechanism and is used for the two trackers in the window.

f5fb0bf297 Prospective Qt linkage fix for macOS 
Try adding an LC_RPATH command to the cdylib that we're building (for example libsixtyfps_cpp.dylib),
to fix linkage against Qt, which uses `@rpath/QtCore.framework/XXX` for inter-library linkage dependencies.

15e0112d2d Qt: Fix image-fit of colorized image

having an empty source rect would cause the scaling to not be right

799b3b16b1 GL backend: Fix clipping with transformations applied to the canvas

in flickable.

abe95688b9 Avoid re-parsing SVG images when scaling in the GL renderer 
This isn't quite 100% clean but keeping a reference to the original svg tree
is maybe a reasonable compromise for now.

fd5757bc44 Simplify coordinate handling for item rendering 
Remove the pos parameter to the render functions and instead let
the item renderer apply the transformation on the rendere (femtovg
canvas or QPainter).

So `draw_*` functions in the backend now always operate in item local
coordinates.

7ac288a849 Fix disappearing html images 
Commit 8a66af0746 resulted in pending html
images not being strongly referenced anymore through the item's
rendering cache when first queried in the image size query. That means
they initially reported a size (1x1) and after loading they *should*
mark the bindings dirty that depend on the implicit size, but since the
image was deleted (and along with it the notifying property), the image
kept its visible (1x1) size.

Similarly, images would get loaded too much from disk - same cause,
different effect.

To fix this, go back to the earlier design where the renderer's image
cache keeps a strong reference.

12b58af1b1 Support rendering SVGs with a specified size in the GL backend 
This is limited to resvg's FitTo::Width though, so the aspect ratio will
always be preserved. This might however be desirable anyway.

8a66af0746 Clean up image size determination in the rendering backend 
Don't use the item's rendering cache to determine the image size, as
that's soley for rendering. The Qt backend doesn't use the item cache
and the GL backend neither after this change. Instead both backends have
a cache for decoded images.
