This way it doesn't have to be stored as DNA runtime pointers or passed
down as a function argument. Currently there is now no property or
button to enable debugging, this will be added again later.
Without this the particle system only shows the actual non-simulated
hairs ("guide hairs") during edit mode. These hairs are used for goals
as well, so showing them in the regular viewport is pretty important.
Also the usual hair curves are interpolated along the entire length,
which makes it very difficult to see exact vertex positions, unless
using exact powers of 2 for the segment number and match the display
steps.

as forces, velocities, contact points etc.
This uses a hash table to store debug elements (dots, lines, vectors at
this point). The hash table allows continuous display of elements that
are generated only in certain time steps, e.g. contact points, while
avoiding massive memory allocation. In any case, this system is really
a development feature, but very helpful in finding issues with the
internal solver data.
Happens because material setting now occurs in the derived mesh drawing
routine as it should. However that means that it also happens during
selection and that influenced the drawing state somehow.
In 2.72 this did not occur because material setting happened during draw
setting (skip or draw) instead of after the draw setting passed (so
selection would skip it by use another draw setting function). Of course
this violated design but worked.
Made it now so backbuffer selection does not enable materials (it's
redundant in those cases anyway).
This could be ported to a possible 'a' release but as is classic with
display code there may be some other places that it could backfire.
Tested fix with texture/vertex painting and selection which use
backbuffer for both subsurf and regular meshes and it seems to work OK.
Basically, our drawing code assumed we always use the edit mesh
materials, which can be different from the derived mesh
materials in modifiers doing overrides. We usually we want to use the
derived mesh when it is available instead.
There are two fixes here for both solid and textured mode. Unfortunately
the fixes do not help to make the display code less labyrinthian but I
expect this "should work" (tm and famous last words)
Solid mode fix is 95% from Bastien, thanks!
This patch creates an interface for selection mechanisms in opengl. This
makes it possible to switch between occlusion query based or select
rendermode based selection transparently.
This is really useful on graphics drivers that do not accelerate the
select rendermode path (some ATI cards are notorious for this, and the
new path is used by default there), since occlusion queries are always
hardware accelerated due to their use in games.
The option can be found under system - selection. Auto just enables
occlusion queries for ATI users while the rest of the options enforce
one of the two methods always.
There is just one known change, previous code enforced nearest bone to
always get selected, even when mouse selecting near the same position, I
couldn't replicate the behaviour though.
patch by me with edits and review by Campbell.
Thanks!
Yep, at last it's here!
There are a few minor issues remaining but development can go on in
master after discussion at blender institute.

Thanks to Sergey and Campbell for the extensive review and to the
countless artists that have given their input and reported issues during
development.
Particles could completely cancel Hide flag! 'Accumulative' bool is not a really good idea here,
hide (or render-hide) are some kind of 'absolute' no-go.
Found another issue in that area, duplicated objects would still show in 'render override' mode,
when object was render-disabled.
Hopefully things are better now.
Objects were hidden in "only render" mode if they were duplicators. This is correct in general, but for particles should be disabled by the "show emitter" option.
