The enumerator values for various GPU compute platforms were
added starting with OIDN 2.0, with the Metal GPU type added
in OIDN 2.2.
This is an alternative fix to ebb781675d, which does not lead to
unhandled cases in switch statement, and follows the configuration
of OIDN and not Cycles (as OIDN might report devices which are
disabled in local Cycles build).

* Only works on machines with a Qualcomm Snapdragon 8cx Gen3 or above.
Older generation devices are not and will not be supported due to
some driver issues
* Requires VS2022 for building.
* Uses new MSVC preprocessor for sse2neon compatibility.
* SIMD is not enabled, waiting on conversion of blenlib to C++.

HIP fails to allocate textures, typically when they are too large.
This commit lets the user know what might be causing the issue
rather than providing a confusing internal error message.

New windows on GNOME with LIBDECOR windowing would sometimes have an
unusable title-bar with the whole title-bar acting as the edge-resize.
Would happen predictably when opening large windows which the window
manager would resize to fit the display.
The cause of this was Blender receiving a window configure event
without a window size for new windows. This configure event
would be ignored, causing the title bar not to work properly.
This is a regression from [0] which removed logic to calculate the
window size from the arguments passed to GHOST for window creation.
This wasn't correct either as the it could temporarily set the
window size before the requested size configuration was received.
Resolve the problem by queuing configuration requests,
handling them then the requested window size is known.

area light with zero spread was introduced in bf18032977. Such paths can
only be sampled with NEE, so MIS should not be used.
This fixes the discrepancy when Direct Light Sampling is set to MIS or NEE.

Adds an option to set the capture title when using renderdoc
`GPU_debug_capture_begin` has an optional `title` parameter to set
the title of the renderdoc capture.

for a camera ray, compute the actual range of the hair width that the
current pixel covers, and only integrate that subset, to prevent a
ribbon-like appearance in close-up looks.
When the hair covers less than one pixel on the screen or when the ray
is not camera ray, the model works the same as before.

The valid interval from incoming direction was shared between
`...eval_r()` and `...eval_residual()`, so compute that in `...eval()` instead.
The valid interval from outgoing direction was computed for
`...eval_r()` to further reduce the integration interval. This part is
removed because the check `dot(wo, wm) > 0` is relatively cheap inside the loop.
The geometry normal of the curve might not be precisely orthogonal to
the tangent due to interpolation. Previously, the tangent was adjusted
to be orthogonal to the normal. However, the normal is linearly
interpolated, which is less accurate than the tangent computed using Catmull-Rom.
This commit keeps the tangent and adjust the normal instead, besides
better accuracy, it ensures a smooth transition when the cross-section
shifts between circular and elliptical.

if emission sampling is not set, we do not use MIS weight when sampling
from the BSDF, but we were still drawing samples from the light,
resulting in double contribution.
