GL_RED texture is used to store the image data.\nNot only this allows to use the same shader code in 10-bit and 12-bit cases.\nBut it also turned out that sampling from GL_RED texture is easier (less\n\"patterns\") than from GL_RGB - even though we loose the \"auto-skipping the LS\nbytes of pixel values\" feature in the 12-bit case.\n\nChanges in v3 vs v2 [1]:\n* Squashed 2/5 and 3/5 into single commit.\n Moved couple comments added in \"Add support for RAW12 packed\" to this commit\n as they are generic, and belong to the initial change.\n* Made stride_ unsigned\n* Dropped unused bayer_8.vert file from \"Add support for RAW8 Bayer\" patch\n\n[1] https://patchwork.libcamera.org/cover/12447/" }
