* app/base/tile-manager.c (read_pixel_data_1): use a temporary
variable to store the return value of tile_manager_get() instead
of assigning to tm->cached_tile directly to make sure
tm->cached_num and tm->cached_tile are always in a consistent
state (the requested tile might be invalid and needs to be
validated, which would call tile_manager_get() recursively, which
in turn would clear the cached tile). Fixes bug #472770.

Applied patch from Zbigniew Chyla that further improves the
boundary_sort() performance (bug #388538):
* base/boundary.c (cmp_xy): use "y" coordinate as more
significant
one, i.e. compare (ay, ax) to (by, bx), not (ax, ay) to (bx,
by).
* configure.in: bumped version to 2.3.19.
svn path=/trunk/; revision=22762
2007-06-11 Sven Neumann <sven@gimp.org>
Applied the second patch from Zbigniew Chyla. Improves
boundary_sort() performance by reducing its time complexity from
O(n*n) to ~O(n*log n) (bug #388538).
* app/base/boundary.c (boundary_sort): prepare two arrays of
pointers to segments, each sorted by different pair of
coordinates ((x1,y1) and (x2,y2)); use new find_segment(),
passing both arrays to it.
(find_segment): new implementation that employs binary search to
find matching segment, using sorted arrays prepared by
boundary_sort().

Implemented an image pyramid for the GimpProjection. An image pyramid
caches a projection at several sizes, causing the rendering code not to
have to swap in all tiles of a (potentially) large image; it can use
small versions of the projection if the user is zoomed out.
The image pyramid also imroves visual quality, especially at zoom levels
where there is a pyramid level that matches perfectly (i.e. at e.g. 50%,
25%, and 12.5% zoom). A step on the right track for bug #76096.
* app/core/gimpprojection.[ch]: Adjusted to make use of an image
pyramid. GimpProjection now keeps an array of TileManager:s, one per
pyramid level. Renamed _alloc_tiles to _alloc_levels.
* app/display/gimpdisplayshell-draw.c: (gimp_display_shell_draw_area):
Use the right GimpProjection level when drawing
* app/display/gimpdisplayshell-render.c: (render_image_init_info_full):
Setup RenderInfo with level in mind
* app/base/tile-manager.[ch]: Extended API a bit, nothing complicated.
* app/base/tile-manager-private.h (struct _TileManager): Keep a pointer
to the level below for use in an image pyramid.

* app/base/siox.c: allocate structs using GSlice.
* app/base/tile-swap.[ch]
* app/xcf/xcf-load.c: removed dead code that used to deal with
swapping from XCF files. Simplified swap file code quite a bit.
svn path=/trunk/; revision=22585
2007-05-22 Michael Natterer <mitch@gimp.org>
* app/base/tile.[ch]: changed tile_init() to tile_new() and return
a GSlice-allocated Tile structure.
(tile_destroy): free it using GSLice.
* app/base/tile-manager.c: use tile_new() instead of g_new plus
tile_init(). Also allocate TileManager itself using GSlice.
* app/xcf/xcf-load.c (xcf_load_parasite): allocate parasites using
gimp_parasite_new().
svn path=/trunk/; revision=22571
2007-05-16 Sven Neumann <sven@gimp.org>
* app/base/tile-manager.c (tile_invalidate): if the invalided tile
is the cached tile, release the cached tile. Fixes bug #438802.

* app/base/gimplut.c
* app/base/gimplut.h
* app/tools/gimpcurvestool.c
* app/tools/gimplevelstool.c: Fixed the value channel color
correction in the curves and levels tools to only modify the
value channel and not the hues. Fixes bug #331782.

2007-04-13 Michael Natterer <mitch@gimp.org>
* app/base/base-types.h
* app/base/temp-buf.[ch]: remove redundant and inconsistently used
MaskBuf type and API.
* app/core/gimpbrush-scale.c
* app/paint/gimpbrushcore.[ch]: use TempBuf and its API instead.
This also optimizes away a useless memset() on brush scaling,
we completely fill each of the created buffers anyway.
svn path=/trunk/; revision=22249
2007-04-01 Michael Natterer <mitch@gimp.org>
* app/base/Makefile.am
* app/base/brush-scale.[ch]: removed these files.
* app/core/Makefile.am
* app/core/gimpbrush-scale.[ch]: added the functions here as
static utility functions. Also move the default implementations of
GimpBrush::scale_size(), ::scale_mask() and ::scale_pixmap() here,
including their utility functions.
* app/core/gimpbrush.c: remove all scale stuff and
include "gimpbrush-scale.h" instead.
(gimp_brush_get_new_preview): use GimpBrush's scale functions
instead of the now private ones. Cleanup.
(gimp_brush_scale_mask)
(gimp_brush_scale_pixmap): return a copy of the buf for
scale == 1.0.
