Immediate Mode: particle_edit.c

`BKE_boundbox_ensure_minimum_dimensions` is no longer necessary

The bug T46099 no longer applies since the addition of `dist_squared_to_projected_aabb_simple`
Has also been added comments that relates to an occlusion bug with the ruler. I'll investigate this.

transform_snap_object: Remove `do_bb` parameter. It is always true

Immediate Mode: area.c and UI_draw_icon_tri, ui_draw_anti_tria

Note: This makes the jittering to not work :/

@merwin, would you know how to use gpuMatrixBegin2D for this case? I
think it must be the reason behind the lack of jittering. But I couldn't
get it to work (the 2D shader is asking for a 3D Matrix).

Immediate Mode: animation markers

Merge branch 'master' into soc-2016-multiview

Alembic: fix naming of imported transforms.

When importing an Alembic file with grouped transforms, it would badly name the transforms, taking the name of the parent instead of its own.

OpenGL immediate mode: Remove unecessary light shader

OpenGL immediate mode: drawarmature.c (end)

No deprecated call left.

OpenGL immediate mode: drawarmature.c (cont)

All (except for stick and wire) are now rendered using batch or immediate API.
Using simple front facing lighting for now, waiting for gpu_basic_shader.c to be recoded.

OpenGL immediate mode: fix inverted normal in sphere batch

OpenGL immediate mode: added gpuRotate3f to GPU_matrix

OpenGL immediate mode: Replacement for gluCylinder

Cycles: Optimize sorting of transparent intersections on CUDA

Cycles: Fix wrong transparent shadows with CUDA

Was a bug in recent optimization commit.

Immediate Mode: timeline cached frames

This involved some refactoring. The original code was relying on a cache of pre-allocated arrays which in turn were still re-populated every redraw loop.

We now ditch those arrays, and make the draw "on the fly".

@merwin can you just check if you foresee any performance impact with this approach?

Cycles: Fix wrong shading on GPU when background has NaN pixels and MIS enabled

Quite simple fix for now which only deals with this case. Maybe we want to do
some "clipping" on image load time so regular textures wouldn't give NaN as
well.

Cycles: Use fast math without finite optimization

This allows us to use faster math and still have reliable
isnan/isfinite tests.

Only do it for host side, kernels stays unchanged.

Thanks Lukas Stockner for the tip!

Refactor writefile handling of data-blocks.

Instead of calling a function looping over whole list of a given ID
type, make whole loop over Main in parent function, and call functions
writing a single datablock at a time.

This design is more in line with all other places in Blender where we
handle whole content of Main (including readfile.c), and much more easy
to extend and add e.g. some generic processing of IDs before/after
writing, etc.

From user point, there should be no change at all, only difference is
that data-block types won't be saved in same order as before (.blend
file specs enforces no order here, so this is not an issue, but it could
bug some third party users using other, simplified .blend file reader
maybe).

Immediate Mode: curve draw stroke

How to test this drawing: create and edit a curve and press shift + drag your mouse (or tablet). The Curve needs a Bevel Depth > 0.0.

Note: The ideal solution would be to use a different shader, that takes
no lighting. However according to Cl�ment Foucault there is an assert preventing the same batch to
me used with different attributes (or something like that). Il wait
until the end of such resolution before revisiting this. That said, it
is working fine.
