Set up work for making a 3.5 prerelease.

Set version stuff to 3.5.0-rc1.
Copy the CHANGELOG from 3.4-working.
Rename the obt-4.0 and obrender-4.0 pkgconfig stuff to obt-3.5 and obrender-3.5
Rename the "render" directory to "obrender" so that the public headers can be
  installed in <obrender/*>

+  that is one or more actual copies of image data at various sizes.  For eg,
+  for a window, all of its various icons are loaded into the same RrImage.
+  When an RrImage is drawn and a picture inside it needs to be resized, that
+  is also saved within the RrImage.
+
+  For each picture that an RrImage has, the picture is hashed and that is used
+  as a key to find the RrImage.  So, given any picture in any RrImage in the
+  cache, if you hash it, you will find the RrImage.
