New description:

 The first patch makes all the `.__attribute` into `._attribute` so that
 the `Graphics` class can be inherited in the future. This is desirable
 since all the important functions are present in this class. One will not
 lose anything in terms of existing functionality.

 The second patch does refactoring of one big bunch of code which is
 present twice in `Graphics().matplotlib()`.

 The third and fourth patches are more of a 'cleanup' nature.

 Passes all doctests in `devel/sage/sage/plot`. (The patches are created
 using 5.0-rc0)
 ----
 Apply patches in this order to `devel/sage`:
 1. [attachment:trac_12974-fix_graphics_attributes.patch] - makes the
 change .__ to ._
 2. [attachment:trac_12974-refactor.patch] - refactoring the tick formatter
 in Graphics.matplotlib
 3. [attachment:trac_12974-reorder_some_arguments.patch] - does the
 reordering of some arguments
 4. [attachment:trac_12974-whitespace_cleanup.patch] - cleans up trailing
 whitespace via the sed function mentioned in comment:4

Comment:

 Sorry for the mixup of the whitespace and refactoring patches - I wasn't
 thinking clearly. I have uploaded the new patches. The whitespace one is
 completely on its own now. The patches are
 1. [attachment:trac_12974-fix_graphics_attributes.patch] - makes the
 change .__ to ._
 2. [attachment:trac_12974-refactor.patch] - refactoring the tick formatter
 in Graphics.matplotlib
 3. [attachment:trac_12974-reorder_some_arguments.patch] - does the
 reordering of the arguments in the dicts. matplotlib is untouched now.
 4. [attachment:trac_12974-whitespace_cleanup.patch] - does the whitespace
 cleanup via the sed function mentioned in comment:4
