v2.4.0v2.4.0
* (Upgrade) EmguCV/OpenCV to v4.5.1
* (Upgrade) AvaloniaUI to 1.0
* (Improvement) GUI re-touched
* (Improvement) Make pixel editor tab to disappear when pixel editor is disabled
* (Improvement) Simplify the output filename from PrusaSlicer profiles
* (Improvement) All operations require a slicer file at constructor rather than on execute, this allow exposure the open file to the operation before run it
* (Improvement) Calibrations: Auto set "Mirror Output" if open file have MirrorDisplay set
* (Change) Tool - Redraw model/supports icon
* (Change) photon and cbddlp to use version 3 by default
* (Add) Tool - Dynamic layer height: Analyze and optimize the model with dynamic layer heights, larger angles will slice at lower layer height
while more straight angles will slice larger layer height. (#131)
* (Add) Calibration - Exposure time finder: Generates test models with various strategies and increments to verify the best exposure time for a given layer height
* (Add) File load checks, trigger error when a file have critical errors and attempt to fix non-critical errors
* Layers must have an valid image, otherwise trigger an error
* Layers must have a incremental or equal position Z than it previous, otherwise trigger an error
* If layer 0 starts at 0mm it will auto fix all layers, it will add Layer Height to the current z at every layer
* (Add) Tool - Edit print parameters: Allow set parameters to each x layers and skip n layers inside the given range.
This allow the use of optimizations in a layer pattern, for example, to set 3s for a layer but 2.5s for the next.
* (Add) Layer height property to "Layer Data" table: Shows layer height for the slice
* (Fix) When automations applied and file is saved, it will not warn user about file overwrite for the first time save
* (Fix) Tool - Redraw model/supports: Disable apply button when no file selected
* (Fix) Tool - Infill: Lack of equality member to test if same infill profile already exists
* (Fix) Auto converted files from SL1 where clipping filename at first dot (.), now it only strips known extensions
* (Fix) SL1 encoded files wasn't generating the right information and lead to printer crash
* (Fix) PrusaSlicer printer "Anycubic Photon S" LiftSpeed was missing and contains a typo (#135)
* (Fix) PrusaSlicer profile manager wasnt marking missing profiles to be installed (#135)
* (Fix) PrusaSlicer folder search on linux to also look at %HOME%/.config/PrusaSlicer (#135, #136)
* (Fix) Operations were revised and some bug fixed, most about can't cancel the progress
* (Fix) Some typos on tooltips
* (Fix) Prevent PhotonS from enconding, it will trigger error now as this format is read-only
* **(Fix) Ctrl + Shift + Z to redo the last operation:**
* The layer range is reseted instead of pull the used values
* Tool - Arithmetic always disabled
* Action - Layer import didn't generate info and always disabled
