so path manipulation functions dont run multiple times on the same path in the case of sequence strips where the one directory is used as the base for many images.
Looks like with current implementation voxeldata should always be created
for voxel textures. Remove recently added NULL check and allocate
voxel data when linking a texture.
- when saving blend file with 'Remap Relative' enabled, don't try make paths absolute if the internal filename is invalid.
- use case insensitive path comparison on windows when checking if path remapping is needed & for comparing next/prev dirs in the file selector.
- use NULL rather then 0 where possible (makes code & function calls more readable IMHO).
- set static variables and functions (exposed some unused vars/funcs).
- use func(void) rather then func() for definitions.
- skip fixing file paths on undo.
- simplify bpath alloc and free functions, also pass Main structure so as not to rely on G.main, (needed for file load).
- loop over sequencer plugin and texture voxel paths.
- fix leak in python bpy.utils.blend_path() and use PyUnicode_DecodeFSDefault() to ensure correct paths with different encodings.
- operators to make paths absolute & relative now redraw the view.
- open operator was incorrectly checking if the font path was set.
- rna ID editable check was also incorrect, checking the ID name rather then the filename.
- use define FO_BUILTIN_NAME rather then "<builtin>".
Both stored the filename of the blend file, but G.sce stored the last opened file.
This will make blender act differently in some cases since a relative path to the last opened file will no longer resolve (which is correct IMHO since that file isnt open and the path might not even be valid anymore).
Tested linking with durian files and rendering to relative paths when no files is loaded however we may need to have some operators give an error if they are used on the default startup.blend.
broke when including the blend path in the modules filename.
- new function BLI_path_basename(), matches pythons os.path.basename().
replace a number of cases where BLI_split_dirfile was being used to get the filename only.
unrelated changes that ended up being more trouble to commit separate...
- removed BLI_split_dirfile(), was nasty, occasionaly modifying the source string, it could create directories and used the $CWD in some cases. was only used in 2 places in filesel.c, if this gives problems can address without bringing back this function.
renamed BLI_split_dirfile_basic --> BLI_split_dirfile
- view3d_operator_needs_opengl was being called for offscreen render when it wasnt needed.
