/**
* This lets you create a drawable based on an XML vector graphic It can be
* defined in an XML file with the <vector> element.
*
* The vector drawable has the following elements:
*
*
* <vector>- Used to defined a vector drawable
* <size>- Used to defined the intrinsic Width Height size of the drawable using
*
android:width and android:height
* <viewport>- Used to defined the size of the virtual canvas the paths are drawn on.
* The size is defined using the attributes
android:viewportHeight
* android:viewportWidth
* <group>- Defines a group of paths or subgroups, plus transformation information.
* The transformations are defined in the same coordinates as the viewport.
* And the transformations are applied in the order of scale, rotate then translate.
* android:rotation
* - The degrees of rotation of the group.
* android:pivotX
* - The X coordinate of the pivot for the scale and rotation of the group
* android:pivotY
* - The Y coordinate of the pivot for the scale and rotation of the group
* android:scaleX
* - The amount of scale on the X Coordinate
* android:scaleY
* - The amount of scale on the Y coordinate
* android:translateX
* - The amount of translation on the X coordinate
* android:translateY
* - The amount of translation on the Y coordinate
* <path>- Defines paths to be drawn.
*
* android:name
* - Defines the name of the path.
* android:pathData
* - Defines path string. This is using exactly same format as "d" attribute
* in the SVG's path data
* android:fill
* - Defines the color to fill the path (none if not present).
* android:stroke
* - Defines the color to draw the path outline (none if not present).
*
* android:strokeWidth
* - The width a path stroke
* android:strokeOpacity
* - The opacity of a path stroke
* android:fillOpacity
* - The opacity to fill the path with
* android:trimPathStart
* - The fraction of the path to trim from the start from 0 to 1
* android:trimPathEnd
* - The fraction of the path to trim from the end from 0 to 1
* android:trimPathOffset
* - Shift trim region (allows showed region to include the start and end)
* from 0 to 1
* android:clipToPath
* - Path will set the clip path
* android:strokeLineCap
* - Sets the linecap for a stroked path: butt, round, square
* android:strokeLineJoin
* - Sets the lineJoin for a stroked path: miter,round,bevel
* android:strokeMiterLimit
* - Sets the Miter limit for a stroked path
