  Formatting.
  
  Cleaning up of ChangeLog.
  
  * docs/license.txt: s/X Windows/X Window System/.
  
  * src/raster/ftraster.c: Fix definition condition of MEM_Set().
  * src/smooth/ftgrays.c (M_Y): Change value to 192.
  * src/base/ftdbgmem.c (ft_mem_table_destroy): Fix printf() parameter.
  Remove unused variable.
  * src/cache/ftcimage.c (ftc_image_node_init,
  ftc_image_node_compare): Remove unused variables.
  * src/cache/ftcsbits.c (ftc_sbit_node_weight): Remove unused
  variable.
  * src/raster/ftraster.c (MEM_Set): Move definition down to avoid
  compiler warning.
  * src/autohint/ahhint.c (ah_hinter_hint_edges): Use UNUSED() to
  avoid compiler warnings.
  * src/pcf/pcfread.c (tableNames): Use `const'.
  (pcf_read_TOC): Change counter name to avoid compiler warning.
  Use `const'.
  * src/pshinter/pshrec.c (ps_hints_close): Remove redundant
  declaration.
  * src/pshinter/pshalgo1.c (psh1_hint_table_init): Rename variables
  to avoid shadowing.
  * src/pshinter/pshalgo2.c (psh2_hint_table_activate_mask): Ditto.
  * src/type1/t1objs.h: Remove double declarations of `T1_Size_Init()'
  and `T1_Size_Done()'.
