FImage is now the standard preferred type for a bag of pixels
FImageView can point at pixels without owning an allocation
ERawImageFormat (FImage) converts to ETextureSourceFormat
FImageUtils provides generic load/save and get/set from FImage
major cleanup in the ImageWrappers
new preferred API is through ImageWrapperModule Compress/Decompress
SetRaw/GetRaw functions cleaned up to not have undefined behavior on unexpected formats
ImageWrapper output added for HDR,BMP,TGA
RGBA32F format added and supported throughout import/export
EditorFactories import/export made more generic, most image types handled the same way using FImage now
Deprecate old TSF RGBA order pixel formats
Fix many crashes or bad handling of unusual pixel formats
Pixel access functions should be used instead of switches on pixel type
