fda8fe40ba 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.

c9d2fee233 capi: support canvas viewport api 
New Experimental API:

090ebfba86 xrenderer/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;

dcf6ebcf18 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.

d27a9782d4 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.
