+Formats in gallium
+==================
+
+Gallium format names mostly follow D3D10 conventions, with some extensions.
+
+Format names like XnYnZnWn have the X component in the lowest-address n bits
+and the W component in the highest-address n bits; for B8G8R8A8, byte 0 is
+blue and byte 3 is alpha. Note that platform endianness is not considered
+in this definition. In C:
+
+ struct x8y8z8w8 { uint8_t x, y, z, w; };
+
+Format aliases like XYZWstrq are (s+t+r+q)-bit integers in host endianness,
+with the X component in the s least-significant bits of the integer. In C:
+
+ uint32_t xyzw8888 = (x << 0) | (y << 8) | (z << 16) | (w << 24);
+
+Format suffixes affect the interpretation of the channel:
+
+- ``SINT``: N bit signed integer [-2^(N-1) ... 2^(N-1) - 1]
+- ``SNORM``: N bit signed integer normalized to [-1 ... 1]
+- ``SSCALED``: N bit signed integer [-2^(N-1) ... 2^(N-1) - 1]
+- ``FIXED``: Signed fixed point integer, (N/2 - 1) bits of mantissa
+- ``FLOAT``: N bit IEEE754 float
+- ``NORM``: Normalized integers, signed or unsigned per channel
+- ``UINT``: N bit unsigned integer [0 ... 2^N - 1]
+- ``UNORM``: N bit unsigned integer normalized to [0 ... 1]
+- ``USCALED``: N bit unsigned integer [0 ... 2^N - 1]
+
+The difference between ``SINT`` and ``SSCALED`` is that the former are pure
+integers in shaders, while the latter are floats; likewise for ``UINT`` versus
+``USCALED``.
+
+There are two exceptions for ``FLOAT``. ``R9G9B9E5_FLOAT`` is nine bits
+each of red green and blue mantissa, with a shared five bit exponent.
+``R11G11B10_FLOAT`` is five bits of exponent and five or six bits of mantissa
+for each color channel.
+
+For the ``NORM`` suffix, the signedness of each channel is indicated with an
+S or U after the number of channel bits, as in ``R5SG5SB6U_NORM``.
+
+The ``SRGB`` suffix is like ``UNORM`` in range, but in the sRGB colorspace.
+
+Compressed formats are named first by the compression format string (``DXT1``,
+``ETC1``, etc), followed by a format-specific subtype. Refer to the
+appropriate compression spec for details.
+
+Formats used in video playback are named by their FOURCC code.
+
+Format names with an embedded underscore are subsampled. ``R8G8_B8G8`` is a
+single 32-bit block of two pixels, where the R and B values are repeated in
+both pixels.
