- Instead of using integers 8, 16, 24, 32 (planes), use an enum ImColorMode (BW, BW_A, RGB, RGBA respectively) and rename the member to color_mode. - Change IMB_allocImBuf to always set color mode to RGBA (that was majority of use cases); code that needs something else can just set color mode separately. - Fix several places were checking "can an image possibly contain alpha" were not handling "grayscale + alpha" (planes==16) case correctly. E.g. VSE was treating a strip with such an image as opaque, and could wrongly occlude strips behind it. - Several image file formats were not roundtripping gray+alpha images correctly, even when they can; that is now fixed. - As a side effect, Jpeg 2000 images can be saved as grayscale (BW) now. - RNA Image.color_mode and color_depth were marked as "enum_bitflag" seemingly by accident, that is no longer so. - IRIS image writing code had option to write "Z" channel that was never used; removed. - Cineon/DPX writing code had an even number of "wrong arguments" being passed to logImageCreate; behavior was fine since the errors cancelled out. - uiTemplateImageInfo had incorrect check for grayscale format display.
