<!-- ##### SECTION Title ##### -->
Image Surfaces
<!-- ##### SECTION Short_Description ##### -->
Rendering to memory buffers
<!-- ##### SECTION Long_Description ##### -->
<para>
Image surfaces provide the ability to render to memory buffers
either allocated by cairo or by the calling code. The supported
image formats are those defined in #cairo_format_t.

<para>
Defined if the image surface backend is available.
The image surface backend is always built in.
This macro was added for completeness in cairo 1.8.
