Originally issue was discovered when using stabilization and movie distortion
nodes, but in fact issue was caused by render layer node always doing nearest
interpolation. Now made it so this node will respect sampler passed to it's
executePixel function and do an interpolation.
Added two new functions to do bilinear/bicubic interpolation in float buffer
with variable number of components per element, so it could interpolate 1, 3
and 4 component vectors. This functions currently mostly duplicates the same
functions from imageprocess.c and it should actually be de-duplicated. Think
it's ok to leave a bit of time with such duplication, since functions should
be generalized one more time to support byte buffers, which could backfire on
readability.
Also removed mark as complex from stabilization node, which isn't needed sine
int fact this node is not complex.
pBVH nodes buffers could share some pointers from pBVH itself,
and after updating pointers in pBVH we need to recreate this buffers.
This starts looking a bit awkward and seems it's mainly because of
assumptions made when was working on sculpting on deformed mesh.
Would revision such a sculpting and would try to make it more clear
later.
Issue was caused by call ED_sculpt_force_update from WM_file_write which frees
derived mesh and pBVH and forces them to be re-created. After this sculpt session
wasn't repairing properly.
Freeing data from WM_file_write is not nice by itself, but it exposed possible
real issue when sculpting on modifiers. Made it so BLI_pbvh_grids_update will
update pointers to material flags and hidden grids as well.
This isn't idea solution for particular circumstances from the report, since
pBVH would be rebuilt after save which ends up with small interface lags for
while pBVH is rebuilding.
Would be nice to have multires displacement propagation to higher levels
without freeing data.
FLT_EPSILON was too small to use when checking if the edge collapse result is an error.
add invert_m3_m3_ex(), invert_m3_ex() functiosn which take an epsilon to check the determinant, saves calculating it twice per edge collapse.
When this new subtypes is used, then string of property is hidden using
asterisks, e.g.: mysecretpassword -> ****************
This code was reviewed and modified by Brecht. Thanks very much:

This new subtype of string property is intended mostly for Add-on developers
writing Add-on which communicates with some server (http, sql, ftp, verse,
etc.). When this server requires user authentication and user has to type
username and password, then current API didn't allow to type 'hidden' password,
e.g. when you want to demonstrate this script, then everybody can see this
security password. Some examples of Add-on which could use this new subtype:
- On-line database of textures
- Integration of render farm
- Integration of Verse
Security Notes:
- You can copy paste hiddent string of property from text input using (Ctrl-C, Ctrl-V),
but you can do this in other GUI toolkits too (this behavior it is widely used).
- Text of string property is stored in plain text, but it is widely used in other
GUI toolkits (Qt, Gtk, etc.).
Simple examples:
- https://dl.dropbox.com/u/369894/draw_op_passwd.py
- https://dl.dropbox.com/u/369894/blender-password.png
Added option to display object's diffuse color multiplied by sculpting
mask. This option could be found in Options panel of toolshelf when in
sculpting mode.
Thanks to Nicholas and Brecht for reviewing the patch!
- use unsigned ints only (where mixing signed/unsigned)
- turn heap_swap into an inline function, add SWAP_TVAL macro to swap values using a temp value as storage.
- added type checking SHIFT3/4 macros
also style cleanup for CTR_Map
- update face normals when triangulating.
- avoid divide by zero when interpolating customdata on a zero length edge.
- replace zero float comparisons with fabsf() < FLT_EPSILON to avoid numeric error.
also renamed BLI_heap_empty() --> BLI_heap_is_empty() so its obviously readonly function.
