- quiet some shadow warnings.
- bevel, ifdef out some asserts that are too common.

Checked the size limit on TGA files in svn history and this is was just an arbitrary limit that might have made sense some years back, but not now.

OpenEXR's ChannelList.layers() will not include empty layer names,
which caused the issue. Made it so if there's one non-empty layer
name, check for empty names happens.
If there's empty layer name in case one non-empty layer name, file
will be considered multilayer now.

also found unintentionally defined enum/struct variables that where only meant to be defining the type.

This commit basically implements frames prefetching for
movie clip datablock.
Number of frames to be prefetched is controlled in User
Preferences, System tab, Prefetch Frames option.
Currently prefetching is destructive-less for movie cache,
meaning mo frames will be removed from the cache when while
prefetching. This is because it's half of simplier to
implement, but it also makes sense from tracking point of
view -- we could want to playback in both directions and
removing frames from behind time cursor is not always a
good idea.
Anyway, smarter prefetching strategy could be developed
later.
Some implementation notes:
- Added MEM_CacheLimiter_get_memory_in_use function to get
memory usage of specified memory limiter.
- Fixed prototype of MEM_CacheLimiter_get_maximum which
was simply wrong (used wrong data type for output).
- Added some utility functions to movie clip and movie
cache for direct cache interaction and obtaining cache
statistics.
- Prefetching is implemented using general jobs system.
which is invoking from clip draw function.
- Prefetcing will stop as soon other job or playback starts.
This is done from performance point of view. Jobs will
likely require lots of CPU power and better to provide
whole CPU to it.
Playback is a bit more complicated case. For jpeg sequence
playback prefetching while paying back is nice. But trying
to prefetch heavy exr images and doing color space
conversion slows down both playback and prefetching.
TODO:
- Think of better policy of dealing with already cached frames
(like when cached frames from other clips prevents frames
from current clip to be prefetched)
- Currently a bit funky redraw notification happens from
prefetch job. Perhaps own ND_ is better to have here.
- Hiding clip while prefetch is active in theory shall stop
prefetching job.
- Having multiple clips opened on file load will prefetch
frames for only one of them.

to integer overflow. One of the beautiful bugs that is sad to see fixed.
Also remove unused timer variable

This makes it so sample line (for all image editor, sequencer and compositor)

before.

paint. Was own regression when optimizing colour operations. I will not
use an alpha bit mask since it may run into portability issues with byte
order.

This commit implements multi-threaded calculation of frames
when building proxies. Both scaling and undistortion steps
are now threaded.
Frames and proxy resolution are still handled one-by-one,
saving files after every single step. So if HDD is not so
fast, this commit could have not so much benefit.
Internal changes:
- Added IMB_scaleImBuf_threaded which scales given image
buffer in multiple threads and uses bilinear filtering.
- libmv's camera intrinsics now have SetThreads() method
which is used to specify how many OpenMP threads to use
for buffer distortion/undistortion.
And yeah, this code is using OpenMP for threading.
- Reshuffled a bit libmv-capi calls and added function
BKE_tracking_distortion_set_threads to specify number
of threads used by intrinscis.

Done by Julien Enche (aka trap), thanks!
From the patch comment:
This patch speeds up Cineon/DPX file loading.
Some more checks are done in dpxOpen and cineonOpen functions so IB_test
flag can now be taken into account safely, and an unnecessary call to
IMB_rect_from_float has been removed.
DPX/Cineon file now loads around 3 times faster on my computer.
Own comment:
Ideally, IB_rect shall indeed indicate which buffers to load, however
currently all places which reads image uses this flag.
This fact already mentioned in OpenEXR reader and it shall be fine
to skip doing rect_from_float in readers themselves.

in case image buffer contains byte buffer only and it's
color space matches display space.
It was already check for this case, but it happened later
in color management routines, which is needed for saving
files, but not fast enough for realtime playback of 4K.

imb_exr_split_channel_name didn't set any value to layer and pass names,

path_util_split_dirstring_2.patch, path_util_split_dirstring_3.patch
from Lawrence D'Oliveiro (ldo)
Get rid of BLI_splitdirstring, replace with calls to BLI_split_dirfile, BLI_split_dir_part and BLI_split_file_part as appropriate.

Add comments and use of bool type in fileops.c
|
|
from Lawrence D'Oliveiro (ldo)
More use of bool type, necessitating adding inclusion of BLI_utildefines.h, or moving it up in the inclusion order if it was already included, in various places
- storage.c: make some variables only used in bli_builddir local to that
- storage.c: BLI_file_descriptor_size should allow 0 as a valid file descriptor
- path_util.c: make pointers to non-reentrant storage returned from folder routines const, necessitating making variables holding these returned pointers const elsewhere as well
- path_util.c: BLI_string_to_utf8 closes iconv context in case of conversion error
- blf_lang.c: fill_locales routine now has its own "languages" local variable to construct paths (was stealing internal storage belonging to BLI_get_folder before)

outside of loop and remove a function call. Should give a little speedup when
painting inside the image editor.

bli_testextensie.patch - from Lawrence D'Oliveiro (ldo)

Before alpha channel was simply ignored causing bad looking
straight colors which is pretty much useless.
Now saving RGB would alpha-over image on top of black color,
which makes final image look really nice. It's also very
such the same what other graphics software does this.
In the future we could easily support configurable backdrop
color, which would be really the same as other SW does it.
Also, it'll probably worth adding the same mode to RGB
display of image editor.

to include a few more that gcc is using too.

16bit PNG and Jpeg2K exporters were not aware of the simple
fact that float buffer could have only 3 or 1 channels.

conflicted with one from IMB_colormanagement.h

style edits and typo corrections.

alpha was used for them which doesn't work for cleaned footage stored
in EXR file format.
Perhaps we need to support configurable alpha mode for clips, but
that's for later (maybe even after release),
|
|
make sure it works if this function gets called from other places.

Adding non-RGBA float buffers as texture crashes MipMap code.
Images with less than 4 channels not supported (yet). Not sure
if we ever should even... normals, Z, vectors, UV, Index, all
don't like downsampling.
|

Used by image painting mode, so every brush step would mark area
if affected on, but actual color space conversion would happen
later when actually displaying image.
Implemented as a rcti stored in ImBuf which is getting merged with
partial rect passed to IMB_partial_display_buffer_update_delayed.
This makes painting as fast as it currently possible and finally
solves #33935: Texture painting slow down with mouse, but not with tablet

Multilayer files saved from Maya (and I bet others) store the 'primary' layer without
layer or pass name, just as R G B A. Allows viewers to show stuff too, I guess.
Blender now reads this as well, just allowing an empty string for the layer and pass.

Issue is solved for painting on byte buffer with default sRGB display enabled.
In this case it is possible to skip any color space transform and just apply
dither if needed.
Still not sure if there's a regression in painting on flaots or not, will
continue investigation.
