The title says it all actually. Use BLI task to loop over vertices
and distort their locations. Gives 2x FPS increase in a file with
just time-dependent displace modifier on my desktop.
This version will give less spin locks and now well-tested by render engines.
This should reduce amount of threading overhead when having multiple objects
with displace modifier enabled.
In the future this will also help us threading the modifier.
There are more modifiers which could benefit from this, but let's first
investigate the new behavior with one of them.
We (the Microsoft C++ team) use the Blender project as part of our "Real world code" tests.
I noticed a place in WIN32 specific code (dvpapi.cpp:85) where a string literal is losing
its const-ness when being passed to BLI_dynlib_open(). This is not permitted when using the
/permissive- conformance compiler switch (see our blog
https://blogs.msdn.microsoft.com/vcblog/2016/11/16/permissive-switch/)
My suggested fix is to add const and propagate it where needed. Another possible fix would be
to explicitly cast away the const.

We had two versions of several BLF functions -- one for a specific font ID & another for the default font.
New BLF_default function lets us simplify this API & delete the redundant code.
There are still many places to fix. I'll miss the bright yellow!
This commit also uses the new BLF_default function where possible.
Part of T49043 since we call glColor less often.
Instead of reference the vertex first and test the bitmap afterwards. Test the bitmap first and reference the vertex after.
In a mesh with 31146 vertices and the entire bitmap disabled, the loop time is 243% faster
With all bitmap enabled, the time becomes 463473% faster!!!
One possible reason for this huge difference in peformance is that maybe the compiler is not putting the function "BM_vert_at_index" inline (I dont know if buildbot do this, but it's good to investigate).
Looks like `object_map` and `mem_arena` may be NULL sometimes...
Also, cleaned up function pointers declaration of Nearest2dUserData,
those were warning out in gcc. Please, *always* use typdef defined
prototypes for function pointers, it is sooooo much cleaner and clearer
that way. And easy to convert from compatible functions too.
BKE_lamp_free was somehow missing the refactor of datablocks handling
(which, among other things, completely separated ID refcounting and
linking management from ID freeing itself).
Either forgot during development, or lost during merge...
The code looks for the closest element between its centers. In the case of islands, the center of each vertex is the center of the island.
The solution here is to skip the search for islands when the operation is translation
-Remove NPOT check as it should be supported by default with OGL 3.3
-All custom texture creation follow the same path now
-Now explicit texture format is required when creating a custom texture (Non RGBA8)
-Support for arrays of textures

Pretty straight forward actually, just do not bother about obdata part
of vgroups in that case, only copy object part of it.
And let's curse once again those stuff spread accross several types of
data-blocks...
Issue was indeed in join operation, mesh in which we join all others
could be re-added to final data after others, leading to undesired
re-ordering of CD layers, and existing vertices etc. being shifted away
from their original indices, etc.
All kind of more or less bad and undesired changes, fixed by always
re-inserting destination mesh first.
Also cleaned up a bit that code, it was doing some rather
non-recommanded things (like allocating zero-sized mem, doing own
coocking to remove a data-block from main, etc.).
Tricky issue caused by CDDM_copy() coying MFACE array but not MTFACE which
confused logic later on.
Now we don't copy ANY tessellation unless it is requested to.
Thanks Bastien for help and review!
blenderplayer uses BLF but not Editor UI, so we got a link error for the missing UI_GetThemeColor function.
Moved the new function from BLF to UI.
@Blendify reported problem in IRC
For anything fancier than regular Theme colors (shading, alpha, etc.) do this:
unsigned char color[4]
UI_GetThemeColor[Fancy]4ubv(... color)
BLF_color4ubv(fontid, color)
That way the BLF color API stays simple.
