d7ab592fb9 lottie: fix repeater order
Assigning numbers 1 or 2 to a bool always
resulted in true. Now fixed and repeated
shapes are drawn in the proper order.
If the repeater had no elements, iterating
shapes from the end would result in a segf.
This issue is now fixed.

8afb7f7ca8 svg_loader: handle text node
The text node is handled, but default values
of the font-family and font-size as used in
the user's system are not.
For now font has to be loaded by the user.

ca92d4a53b lottie: fix matte layer finding
Layer identifiers do not have to be unique within
the entire file - they are unique within a given
group. Searching the entire composition to find
the referenced matte was an incorrect approach.

7b9bebe1de lottie: repeater transformation fix
In the case of a transformation (denoted as T1)
appearing after the repeater, but at the same
level of nesting, the objects to which the repeater
is applied should not consider T1. However,
the transformation of the repeater itself should
take T1 into account.
Also, it is possible to have several consecutive
repeaters, and all of them should be taken into
account. Until now, the last one was overwriting
the previous one.

1ee79a6c2a lottie: add 'tp' tag support
So far it hasn't been possible to specify
a matte layer - by default, it was the layer
above the calling layer. The 'tp' tag support
has been introduced, enabling referencing any
layer by its index.
In cases where the layer referencing the matte
was the first one, a segmentation fault was
observed. This issue has now been resolved.

ed14966144 svg_loader: move the display property to the style
The display property, like any other node's style property,
should be part of a node style. This ensures its correct
copying and inheritance.
For the 'symbol' node, which is not rendered unless it is
used within a 'use' node, the display property can also be
applied. Because of that it cannot be utilized during scene
construction to determine whether the symbol is being defined
or used within a 'use' context.
