A single vertex attribute defined by its <A HREF="../../../../com/badlogic/gdx/graphics/VertexAttributes.Usage.html" title="class in com.badlogic.gdx.graphics"><CODE>VertexAttributes.Usage</CODE></A>, its number of components and its shader alias. The Usage is needed for
the fixed function pipeline of OpenGL ES 1.x. Generic attributes are not supported in the fixed function pipeline. The number
of components defines how many components the attribute has. The alias defines to which shader attribute this attribute should
bind. The alias is used by a <A HREF="../../../../com/badlogic/gdx/graphics/Mesh.html" title="class in com.badlogic.gdx.graphics"><CODE>Mesh</CODE></A> when drawing with a <A HREF="../../../../com/badlogic/gdx/graphics/glutils/ShaderProgram.html" title="class in com.badlogic.gdx.graphics.glutils"><CODE>ShaderProgram</CODE></A>. The alias can be changed at any time.
