* Updated to the latest guest release: crt-guest-advanced-2022-07-27-release1
* Changed Guest mask size to 1 by default so that there isn't inconsistency using guest settings in the Mega Bezel
* Adjusted the default SMOOTH-ADV scaling parameters for a sharper smooth look:
* HSM_CORE_RES_SAMPLING_MULT_SCANLINE_DIR = 300
* HSM_CORE_RES_SAMPLING_MULT_OPPOSITE_DIR = 125
* HSM_DOWNSAMPLE_BLUR_SCANLINE_DIR = 0
* HSM_DOWNSAMPLE_BLUR_OPPOSITE_DIR = 0
* Added **Shift Sampling Relative to Scanlines** to shift the image relative to the scanlines
* The ScaleFx settings now only appear on the SMOOTH-ADV preset nearer the bottom of the parameter list
* Fixed Double image when using cropping in NTSC presets reported by @JHorbach1
* Updated to crt-guest-advanced-2022-07-17-release1
* Includes Scanline Gamma
* Tube Gel and Diffuse Fixes
* Gel is now mapped to the tube, independent of the black edge
* Added a feature to add a bit of tube diffuse shading to the GEL this should make it look a little more natural
* [ TUBE COLORED GEL IMAGE ] > Normal Multiply by Tube Diffuse Shading
* HSM_TUBE_BLACK_EDGE_LAYERING_MODE has been removed as it's not needed anymore
* CRT Multiply blend mode now works better when there is extra tube thickness
* Changed HSM_TUBE_DIFFUSE_IMAGE_SCALE to 120 by default to have a less rounded look
* If you want a stronger rounded shaded look reset it to 100
* Fixed Scale discrepancy when using the Cab Glass Image
* Added Shadow Opacity param to control shadow being applied to the static tube highlight
