Added new Nearest Neighbor image scaling algorithm for optimized render performance.
Speedup opaque color blit on 16 bit framebuffer when using DMA2D.
Speedup opaque color/bitmap blit on 16 bit framebuffer when using GPU2D.
Better utilization of DMA2D for text rendering.
Added libraries for cortex M85.
Added libraries for ST Arm Clang toolchain.
Updated arm gcc compiler to version 13.3.1.
Updated Windows gcc compiler to version 13.2.0.
Bugfixes in TouchGFX Core:

Fixed compiler warning in AbstractPainterColor and AbstractPainterBitmap constructor.
Fixed a bug in Bitmap::dynamicBitmapCreateExternal() where RGB565 images where not drawn correctly.
Fixed bug in ScrollableContainer where scrollbars had wrong size.
Fixed generated formatting conflicts in project file when using STM32CubeIDE project updater.
Changed default to use byte-aligned fonts on GPU2D (NeoChrom) targets.
Fixed synchronization bug when drawing L8 images on targets with DMA2D (ChromArt) and GPU2D (NeoChrom).
Fixed SVG rendering bug when having a larger framebuffer stride than display pitch on targets with GPU2D (NeoChrom).
The generated typedTextDatabaseArray[], which might contain pointers to external flash, is now placed in internal flash by default.
Touchgfx libraries for other platforms than the current target are no longer included in the project when generating code.
Deprecated TouchGFX Core Features:

AbstractPainterBitmap::AbstractPainterBitmap(const Bitmap& bmp = Bitmap(BITMAP_INVALID)) has been replaced with AbstractPainterBitmap::AbstractPainterBitmap(). This applies for all Bitmap Painter constructors.
