Subdiv: Fix wrong corner passed to a callback

Multires: Simplify reshaping code

The idea is to run reshaping for every boundary vertex
of a grid rather than trying to copy boundary grid
elements.

While this is somewhat slower, this avoids all this
tangent flipping magic, which tempts to be rather tricky
and fragile.

Multires: Correct function name, to match behavior

Multires: Fix spike issues when sculpting on triangles

The boundary copy code was not dealing correct with flipping
tangent vectors, hence causing discontinuity in the final
positions.

Now we only copy boundaries for quads, where we know how to
deal with tangent vectors and where we know that this is
needed.

More clear solution could be to change the code in a way that
handles handles displacement grids of quads in the same way
as it's done for non-quad faces.

Multires: Cleanup, move utility function to a more public place

Multires: Cleanup, more clear naming

GP: Create materials when separate active layer

The materials were not created when used the active layer option of the separate operator.

DRW: Increase frustum culling precision

Use normal_quad_v3 instead of normal_tri_v3 and compute the mean of all
corner distance during frustum plane extraction.

Fix T58243 Flickering of viewport when rotating and zooming

DRW: Fix assert when using draw debug API

Fix T60608: Popup dialogs Y-axis reset after drag

Caused by fc32bd729c5b7

3D View: Disable clipping on load

Having clipping limit selection and tools is confusing when not visible.

Disable on load until it's supported
(doing this via ifdef's isn't practical).

Fixes T59580

Cycles: Cast to correct base type when checking requested features

Cleanup: use enum for color picker types

Fix eye-dropper causing undo push w/o any changes

Happened when accessing the eyedropper from a popup.

Fix undo pushes w/ color picker

While changing RGBA or color wheel didn't add undo steps,
HSV and Hex values did.

Disable undo for these button types since an undo push happens when
exiting the picker.

Fix T56799: Custom render passes missing when using Save Buffers

The problem here was that when a render result is allocated, the standard render passes are added according to the
pass bitfield. Then, when the render engine sets the result, it adds the additional passes which are then merged
into the main render result.

However, when using Save Buffers, the EXR is created before the actual render starts, so it's missing all those
additional passes.

To fix that, we need to query the render engine for a list of additional passes so they can be added before the EXR
is created. Luckily, there already is a function to do that for the node editor.

The same needs to be done when the EXR is loaded back.

Due to how that is implemented though (Render API calls into engine, engine calls back for each pass), if we have
multiple places that call this function there needs to be a way to tell which one the call came from in the pass
registration callback. Therefore, the original caller now provides a callback that is called for each pass.

Render API: Fix detection of duplicate render passes

UI: only reset eyedropper on cancel when set

Fix color picker cancel setting the color to black
