Darktable 4.0.1

What's new in this version:

Changed:
- Variables $(MAKER) and $(MODEL) can now be used when importing files
- Display infinity for very large focus distance as supported by the
exif standard

Fixed:
- Fix overexposed indicators after cropping
- Fix DNG creation in the HDR merge module (ColorMatrix could be zero)
- Fix culling layout, which could be broken after a second use when changing the number of images (e.g. when rejecting an image)
- Fix GUI reset of the export module when using TIFF format
- Fix copy of iop-order in merge mode when multiple instances are used in the destination images
- Fix color filtering issue on Windows
- Fix possible black screen when using auto-white balance on Windows
- Properly retain the access and modified timestamps when using copy and import
- Fix color picker reset in color zones module
- Fix help link for module layout management
- Fix crash after a failed camera tethering attempt
- Add support for fast pipe mode on the diffuse module. Fast pipe mode is used to bypass long-running modules while interactively changing another module's parameters where that module does not require accurate image display.
- For example, it is used to improve responsiveness of the on-screen display in the crop and rotate/perspective modules
- Fix some color picker button action types
- Fix crash in Latex export
- Fix website gallery export
- Fix a file-handle leak
- Fix a memory corruption in sharpen module that could lead to a crash
- Fix vectorscope histogram display to avoid cropping the primary and secondary nodes (top and bottom)
- Add HEIF media type association for the desktop
- Fix possible crash when using the color checker without a properly selected patch
- Fix sorting of LUT 3D files and left-align the entries for better readability
- Disable upscaling when export size is set to original image dimensions (0) as this does not have meaning and could crash darktable
- Fix possible crash when applying a time-offset to images
- Fix crop-size information displayed on screen (rounding issue)
- Fix blending detail mask memory requirement
- Fix crash when zooming with fingers on an empty lighttable
- Ensure that external format size limits are enforced during export
- Some CSS fixes on color, contrast, positioning of combo-boxes, check-box size, scrollbars and progress bars
- Fix JPEG APP1 header (skip 6-byte header)
- Fix some missing translations in notebook tabs
- Use a color-managed background for color balance rgb module sliders
- Light up midi modifier keys when shift/ctlr/alt are pressed
- Some speed improvements (tuned compiler options, some optimized routines)
