* Gray2Rgb
* MedianFilter
* MorphoDilate
* MorphoErode
* Rgb2Gray
* Rgb2Hsv
* Rgb888ToRgb565
* Rgb888ToUYVY

* New OpenGL ES3 samples
* System.Gestures
* UI.RenderTest
* UI.Gestures
* New Vulkan samples
* System.EasingFunctions
* System.Gestures
* UI.RenderTest
* UI.Gestures
* Added new demo app templates
* OpenGLES3.HDR
* Vulkan.HDR
* New OpenGL ES 2+3 command line arguments
* ```--EGLSampleBuffers <arg>``` Force EGL_SAMPLE_BUFFERS to the given value
* ```--EGLSamples <arg>``` Force EGL_SAMPLES to the given value
* FslSimpleUI
* Reworked the way colors are handled so we can better support SRGB and HDR rendering.
* All control color properties are now represented by UIColor instead of Color (16bit per channel and color space info).
* Rendering uses UIRenderColor which stores the colors using 16bit per channel mathing the frame buffer format (linear/non-linear).
* Basic gesture support.
* Basic scroll view with gesture support.
* FslSimpleUI.Delcarative updated to support most controls, it can also now dump a xsd from code describing the possibilities.
* The default theme texture atlas is now generated in two versions
* NonLinear (premultiply alpha is done directly on the non-linear SRGB colors, like we used to do)
* Linear (premultiply alpha is done by transforming the RGB colors to linear values and applying the alpha, then converting back to non-linear).
* Support for line rendering for charts.
* Misc
* Clang tidy now enforces naming conventions.
* HDR screenshot support.
* ImageConverter service updated.
* Added FslDemoService.ImageConverter.HDR service.
* Added FslGraphics2D.PixelFormatConverter package.
* BasicRender line list+strip support.
* Stats sample now show CPU chars (GLES2, GLES3, Vulkan).
* TightBitmap added for the cases where you need to work on bitmap data where the data is tighly packed in memory.
* ```StringViewLite``` now utilize a ```std::string_view``` internally.
* ```ReadOnlySpan``` now utilize a ```std::span<const T>``` internally.
* ```Span``` now utilize a ```std::span<T>``` internally.
* Updated easing function in FslBase
* Many old classes now utilize span's instead of pointer, length.
* UIDemoAppLegacyExtension was removed and all samples using it updated to use UIDemoAppExtension.
