e409bb2984 svg_loader: LumaMask used only for masks other than white 
For the performance reasons, the LumaMask is used only when
it's necessary - when the mask color is other than white.
Otherwise the AlphaMask is enough.

2f7e7e9923 svg_loader: mask-type attribute introduced 
In an svg file the mask-type attribute can be specified.
It takes one of the two values: Luminosity or Alpha.
After the LumaMask is introduced into TVG, this attribute can be
properly read by the svg loader.

a6781734dc svg_loader: composite node splitted on mask and clip nodes 
The SvgCompositeNode is replaced by the SvgMaskNode and SvgClipNode.
This is needed for using Luma/AlphaMask in the svg loader and in the future,
when we introduce other mask's features.

4485db4f15 svg_loader: a function to establish shapes boundries without a stroke introduced 
To handle the objectBoundingBox units, the shape's boundaries have to be known.
According to the SVG standard, a stroke shouldn't be taken into account. Since
the bounds() api uses the shape's stroke information, a new function is introduced,
that compensates this and returns boundaries without any strokes.

are introduces in this commit.

875e200767 common: code refactoring 
removed invalid nullptr checks.

New allocation doesn't gurantee that returns nullptr when it's failed.
It's useless on the modern compliers and our policy respects it.

1.
Remove macro function. The existing macro function
was doing meaningless nested `return false`.

2.
Extract the logic to find the type as a function.

3.
The SimpleXMLType::Error case is not actually used,
and in case of invalid XML, Do 'return false' immediately.
