* app/base/tile-pyramid.[ch] (tile_pyramid_new): changed "type"
parameter into "bytes" because tile managers don't care about
the pixel format of their tiles. Reordered parameters to match
tile_manager_new().
* app/core/gimpprojection.c (gimp_projection_get_tiles_at_level):
pass the bytes instead of the image type.

* app/base/tile-pyramid.c: use the coordinate parameters in
tile_data_pointer() instead of adjusting the pointer manually.

* app/base/tile-pyramid.c (tile_pyramid_write_quarter)
* app/display/gimpdisplayshell-render.c
(render_image_tile_fault_nearest): corrected formula used for
pre-multiplying the alpha value.

Speed up our display rendering code paths by keeping data with
pre-multiplied alpha where possible. The projection tile-manager
at 100 % zoom is not affected. So we can still always get the
non-pre-multiplied pixel data.
* app/core/gimpprojection.[ch]: removed
gimp_projection_get_opacity(), the projection is always opaque.
* app/base/tile-pyramid.[ch]: use pre-multiplied alpha for the
upper levels of the pyramid. This speeds up validation of the
upper levels significantly.
* app/base/temp-buf.[ch]: added temp_buf_demultiply().
* app/core/gimpimage-preview.c: demultiply the preview temp-buf
obtained from the projection's tile tyramid.
* app/display/gimpdisplayshell-draw.c
* app/display/gimpdisplayshell-render.c: added code to deal with
pre-multiplied data. In fact all data returned by
render_image_tile_fault() is now pre-multiplied so that
render_image_rgb_a() and render_image_gray_a() don't need to use
the large lookup tables from gimprender.[ch] any longer.

* app/base/tile-manager.[ch]
* app/base/tile-manager-private.h: removed "level_below" from the
TileManager struct.
* app/base/tile-pyramid.c: use the TileManager's user_data to
store a pointer to the lower level.

* app/base/tile-manager.[ch]: use gboolean for boolean parameters.
* app/base/tile-pyramid.c (tile_pyramid_get_memsize): pass TRUE
for sparse to tile_manager_get_memsize().
* app/base/tile.c
* app/base/tile-swap.c: minor cleanups.
* app/core/gimpprojection.c (gimp_projection_get_tiles_at_level):
inline the creation of the TilePyramid.

* app/base/tile-pyramid.c (tile_pyramid_write_quarter): added missing
implementations for 1 and 3 bytes per pixel.

* app/base/Makefile.am
* app/base/base-types.h
* app/base/tile-pyramid.[ch]: image pyramid code split out of
GimpProjection.
* app/core/gimpprojection.[ch]: use the new TilePyramid.
