Applied a patch from Øyvind Kolås that adds supersampling to the
transform operations (bug #109817):
* app/base/tile-manager-private.h
* app/base/tile-manager.[ch]: cache the last accessed tile and use
it to optimize read_pixel_data_1().
* app/core/gimpdrawable-transform-utils.c
* app/core/gimpdrawable-transform.c: changed the resampling
behavior when scaling down.

Fixed#10466 (disappearing pixels when rotating by 90 deg):
* app/core/gimpdrawable-transform.c: when transforming backwards
to find the destination line's sub-pixel source coordinates, we
need to transform the pixels _center_, not it's upper left corner.
* app/core/gimpdrawable-transform-utils.[ch]: added
gimp_drawable_transform_matrix_rotate_center() which takes double
center coordinates instead of an integer pixel bounding box.
* app/tools/gimptransformtool.[ch]: use double instead of int for
all coordinates except the original bounding box.
* app/tools/gimprotatetool.c: use double whenever touching the
"center" value, so it can be sub-pixel positioned.

* app/display/gimpdisplay-foreach.c: forgot to commit last time.
Transform stuff cleanup:
* app/core/Makefile.am
* app/core/core-types.h
* app/core/gimpdrawable-transform.[ch]: new files implementing
the actual transform functions cut from tools/gimptransformtool.*.
* app/core/gimpdrawable-transform-utils.[ch]: new files implementing
transform matrix assembly utility functions.
* app/tools/gimptransformtool.[ch]: removed the stuff here. cleanup.
* app/tools/transform_options.[ch]: removed all stuff which does
not belong here, e.g. the transform_tool_* functions and the
global "transform_options" variable. Works like all other tool
options now.
* app/tools/gimpfliptool.[ch]
* app/tools/gimpperspectivetool.[ch]
* app/tools/gimprotatetool.[ch]
* app/tools/gimpscaletool.[ch]
* app/tools/gimpsheartool.[ch]: massive code removal because
we can use core/gimpdrawable-fransform* functions now. cleanup.
* tools/pdbgen/Makefile.am
* tools/pdbgen/groups.pl: added new PDB group "transform_tools".
* tools/pdbgen/pdb/tools.pdb: removed the transform stuff here...
* tools/pdbgen/pdb/transform_tools.pdb: and added *much*
simplified versions which use the new core/gimpdrawable-transform*
utilities.
* app/pdb/Makefile.am
* app/pdb/transform_tools_cmds.c: new file.
* app/pdb/internal_procs.c
* app/pdb/tools_cmds.c: regenerated.
* libgimp/Makefile.am
* libgimp/gimp_pdb.h
* libgimp/gimptransformtools_pdb.[ch]: new files.
* libgimp/gimptools_pdb.[ch]: regenerated.
