Subject: [PATCH] Lower gamma_correct so the LEDs dim below 28/255
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

gamma_correct defaults to 2.8, and calculate_gamma_table() computes
round((i/255)^gamma * 255), so indices 0 through 27 all map to 0. Below
28/255 the LEDs were driven fully off rather than dim, while the entity
still reported on.

1.5 brings the first lit value down to 4/255 and keeps a perceptual
curve rather than going fully linear.

Set on the partitions because that is the correction that applies:
light_partition.h get_view_internal() calls raw_set_color_correction()
with the partition's own correction for every pixel it writes, so the
parent chain's value would be inert.

Version 26.8.26.4
