The CSS API uses a lot of nested anonymous structs defined in object
macros to assign default values to its data-structures.  These have been
changed to use compound-literals and designated initializers to make
them more comprehensible and less fragile.

The compound-literals can also be used in assignment, which means we can
get rid of some temporary variables whose only purpose is to be
initialized by one of these anonymous structs and then serve as the
rvalue in an assignment expression.
