The vert-origin-x attribute indicates the x-coordinate in the font coordinate system of the origin of a glyph to be used when drawing vertically oriented text.

The viewBox attribute defines the position and dimension, in user space, of an SVG viewport.

The repeatDur attribute specifies the total duration for repeating an animation.

The <feColorMatrix> SVG filter element changes colors based on a transformation matrix. Every pixel's color value [R,G,B,A] is matrix multiplied by a 5 by 5 color matrix to create new color [R',G',B',A'].

The <feFuncB> SVG filter primitive defines the transfer function for the blue component of the input graphic of its parent <feComponentTransfer> element.

Now that we covered the basics of the SVG internals, we will take a look at some tools to work with SVG files.

There are several basic shapes used for most SVG drawing. The purpose of these shapes is fairly obvious from their names. Some of the parameters that determine their position and size are given, but an element reference would probably contain more accurate and complete descriptions along with other properties that won't be covered in here. However, since they're used in most SVG documents, it's necessary to give them some sort of introduction.
