SVG - Janvas Layer
Janvas layers are SVG "g" nodes placed inside the "layers" node of the page content.
A layer must have some added attributes to be loaded and parsed as Janvas layer.
As you can see into the SVG XML code the SVG layer tag have these attributes:

-  data-name = ( the name of the layer )
-  data-color = ( the color of the layer )
-  class="layer"

<!-- page layers -->
<g class="layers">
<!-- layer -->
<g transform="matrix(1,0,0,1,0,0)"
data-name="Layer 1"
<!--- graphics elements -->

The layers panel shows the list of layers present in the current page.
