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 v2 vs v1 [1]:\n* bayer_8.frag: fixed a bug of using F1 value instead of E1, and E1 value\n instead of F1. This error is present in the pixel shader listing in [2],\n and seems to have got into at least one project [3] from there.\n\n[1] https://patchwork.libcamera.org/cover/11387/\n[2] https://casual-effects.com/research/McGuire2009Bayer/index.html\n[3] https://github.com/motmot/libcamiface/blob/master/demo/demosaic.frg" }
