9a455632a2 lottie: matrix multiplication fix 
In case the shapes could be merged, matrix
multiplication was not stored in any variable,
resulting in one of the transformations not
being applied.

7ea17d4e72 capi: support canvas viewport api

42409987e2 renderer/engines: support the canvas viewport function. 
The viewport function defines the rectangular area of the canvas
that will be used for drawing operations.

It is used to clip the rendering output to the boundaries of the rectangle.
Apps can use this function to set the drawing region within the canvas.

When the ThorVG canvas is partially inside the screen area such as during scrolling
it could help enhance rendering performance.

New Experimental API:
- Result Canvas::viewport(int32_t x, int32_t y, int32_t w, int32_t h) noexcept;

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.

8c4879f15d common: fix a precision issue in appendArc api 
For angles close to multiples of pi/2, precision
based on FLT_EPSILON was insufficient. It either
led to the creation of an additional cubic segment
filled with erroneous values or NaNs, or it resulted
in the drawing of an angle for a sweep close to 0.
