# This CSV file has the input data for u_format.h's struct
# util_format_description.
#
# Each format entry contains:
# - name, per enum pipe_format
# - layout, per enum util_format_layout, in shortened lower caps
# - pixel block's width
# - pixel block's height
# - channel encoding (only meaningful for plain layout), containing for each
#   channel the following information:
#   - type, one of
#     - 'x': void
#     - 'u': unsigned
#     - 's': signed
#     - 'h': fixed
#     - 'f': FLOAT
#   - optionally followed by 'n' if it is normalized
#   - number of bits
# - channel swizzle 
# - color space: rgb, yub, sz
