Brad King d71db3a0d8 FindSDL: Make FindSDL_*.cmake path suffixes consistent with main module
Add the 'SDL' path suffix to the FindSDL_*.cmake modules.  Add a comment
explaining the purpose of suffixes as in commit v3.0.0-rc1~540^2
(FindSDL: Add path suffixes for <prefix>/include/..., 2013-10-08).

#.rst:
# FindSDL_ttf
# -----------
#
# Locate SDL_ttf library
#
# This module defines:
#
# ::
#
# SDL_TTF_LIBRARIES, the name of the library to link against
# SDL_TTF_INCLUDE_DIRS, where to find the headers
# SDL_TTF_FOUND, if false, do not try to link against
# SDL_TTF_VERSION_STRING - human-readable string containing the version of SDL_ttf
#
#
#
# For backward compatiblity the following variables are also set:
#
# ::
#
# SDLTTF_LIBRARY (same value as SDL_TTF_LIBRARIES)
# SDLTTF_INCLUDE_DIR (same value as SDL_TTF_INCLUDE_DIRS)
# SDLTTF_FOUND (same value as SDL_TTF_FOUND)
#
#
#
# $SDLDIR is an environment variable that would correspond to the
# ./configure --prefix=$SDLDIR used in building SDL.
#
# Created by Eric Wing. This was influenced by the FindSDL.cmake
# module, but with modifications to recognize OS X frameworks and
# additional Unix paths (FreeBSD, etc).
