Tab art provider defines all the drawing functions used by wxAuiNotebook.

This allows the wxAuiNotebook to have a pluggable look-and-feel.

By default, a wxAuiNotebook uses an instance of this class called wxAuiDefaultTabArt (not implemented in wx) which provides bitmap art and a colour scheme that is adapted to the major platforms' look. You can either derive from that class to alter its behaviour or write a completely new tab art class.

Another example of creating a new wxAuiNotebook tab bar is wxAuiSimpleTabArt.

Call wxAuiNotebook:setArtProvider/2 to make use of this new tab art.
