Cleanup: Remove unused variable in kernel_path_volume_bounce().

Cycles: Avoid redundant call to volume_stack_is_heterogeneous() for Distance Sampling.

Cycles: Avoid call to volume_stack_sampling_method() on GPU, Decoupled is required for Equi-Angular/MIS.

Cycles: Remove Volume Nodes GPU warning and gray out Sampling Method button when using GPU.

Fix T41548: Menu pulldown button behaves incorrectly on click if menu shadow width is set to 0 in theme prefs.

This is more like a workaround actually, we use a fixed 'margin' for height in case of search menus,
instead of using shadow width (which gave the bug with low values, and insane margins with big ones).

Note root of the issue is that if 'top' margin is too small, the first entry of the search menu
gets activated before the 'opening' click is released. This means that button will get the
KM_RELEASE event, and immediately quit (see interface_handlers.c:7945, ui_handle_menu_button()).

Fix T41550: Python: frame_set skips frame -1; frame_set(n) sets to frame n-1 for (only) negative number n, and sets to frame n for non-negative number n.

This appeared in rBrB94cb20ff4e78b, purposedly it seems, but without even
a single line of comment to explain why this was needed. For now, remove it.

ColorRamp: remove linear/srgb conversions

Turns out these aren't needed

gameengine: fix T41272 - KX_Light.color returns wrong values

Fix T41538: Sun Beam Node has artifact at its radius.

The sunbeams node was clamping the range of influence to start at 1
pixel distance from the source. This was a poor fix for artifacts caused
by an off set in buffer coordinates. Since the u coordinate starts at
ceil(umax) the v coordinate also has to use ceil. This also fixes some
discontinuities that became visible when the source point is close to
a sharp line in the input image.

Smallhash: BLI_smallhash_calc_quality

Also add inline hashing function to measure different methods.

BGE: fix crash and return boolean on scene.replace()

Scene replacement with invalid scene name was crashing blender,
now it's a no-op.
KS_Scene.replace() to return a boolean to indicate if the scene
is valid and is scheduled for replacement. This allows more
robust game management.

Fix T41541: Cuda renders objects in black with MIS enabled in world setting

Issue introduced in 8d3cc431d7fdcc9f3243cc24dfdcb94124be0993, parameter mismatch.

Cycles: DPX is saved in the sRGB space and need to be converted to linear

This at least applies to DPX saved from within blender, which is 1st prio
to support working reliably.

Fix missing tag for detecting changes with bpy.data.node_groups[...].is_updated.

Cycles: Fix wrong image update tagging, float vs. byte images

Fix T41068: 3D viewport shading - Material or Window vs. Rendered

Checked with Brecht, Cycles indeed expects generated to be in 0..1 space
instead of -1..1 as it is in BI.

Cleanup: BMesh arg name

Fix T41528: Error message on trying to import COLLADA triangle strips is wrong

Thanks to Maarten Gribnau for the patch.

ColorRamp: Use linear V for HSV/HSL blending

This matches RGB blending black/white for eg.

ColorRamp: HSV CW/CCW were flipped
