How to fill shape bodies with texture effects?

[魏学超 <wei xuechao gmail com>]

Hello, Dia maintainers,

   I really need some texture effects, marble etc. to visualize the shapes in my drawing, but I haven't found any button or toolbar to achieve this.
   So I want to ask which part of the panel to help me, or Dia has not realized this function.

Sincerely, weixuechao.
