/**
* @short The <code>text</code> element defines a graphics element
* consisting of text.
*
* The XML character data within the <code>text</code> element, along
* with relevant attributes and properties and character-to-glyph
* mapping tables within the font itself, define the glyphs to be
* rendered. (See <a
* href="http://www.w3.org/TR/SVG/text.html#CharactersAndGlyphs"> Characters
* and their corresponding glyphs </a>.) The attributes and properties on the
* 'text' element indicate such things as the writing direction, font
* specification and painting attributes which describe how exactly to render
* the characters. Since <code>text</code> elements are rendered using the
* same rendering methods as other graphics elements, all of the same
* coordinate system transformations, painting, clipping and masking
* features that apply to tqshapes such as paths and rectangles also
* apply to <code>text</code> elements.
*
* It is possible to apply a gradient, pattern, clipping path, mask or
* filter to text.When one of these facilities is applied to text and
* keyword objectBoundingBox is used to specify a graphical effect
* relative to the "object bounding box", then the object bounding box
* units are computed relative to the entire 'text' element in all
* cases, even when different effects are applied to different 'tspan'
* elements within the same 'text' element.
*
* The <code>text</code> element renders its first glyph (after <a
* href = "http://www.w3.org/TR/SVG/text.html#RelationshipWithBiDirectionality"
* >bidirectionality</a> reordering) at the initial current text
* position, which is established by the <code>x</code> and
* <code>y</code> attributes on the <code>text</code> element (with
* possible adjustments due to the value of the @ref text-anchor
* property, the presence of a @ref textPath element containing the
* first character, and/or an <code>x</code>, <code>y</code>,
* <code>dx</code> or <code>dy</code> attributes on a @ref tspan, @ref
* tref or @ref altGlyph element which contains the first character).
* After the glyph(s) corresponding to the given character is(are)
* rendered, the current text position is updated for the next
* character. In the simplest case, the new current text position is
* the previous current text position plus the glyphs' advance value
* (horizontal or vertical).
*
* @see SVGShape
* @see SVGTextPositioningElement
*
* For more info look here : <a href =
* "http://www.w3.org/TR/SVG/text.html#TextElement"> 10.4 The
* 'text' element</a>.
