* empty * docs: flesh out 31 TBW efun reference pages Replace the placeholder "TBW" DESCRIPTION and type-only SYNOPSIS in 31 efun docs with real descriptions and named parameters, verified against the driver source: - math (general/): log10, log2, norm, dotprod, distance, angle - matrix (general/): id_matrix, translate, scale, rotate_x/y/z, lookat_rotate, lookat_rotate2 -- note the in-place mutation of the passed matrix and that rotations are in degrees - compress (general/): compress, uncompress, compress_file, uncompress_file -- note the file variants delete the source on success - interactive/: send_zmp, act_mxp, request_term_type, start_request_term_type, request_term_size - internals/: dump_trace, destructed_objects, check_memory (flag bitmask + DEBUGMALLOC build requirement), dump_stralloc, dump_jemalloc - core: next_bit, explode_reversible, shallow_inherit_list Each page keeps the existing manpage-style layout (4-space-indented NAME/SYNOPSIS/DESCRIPTION, name(3) SEE ALSO). Example blocks are indented to match, so all files are markdownlint-clean.

scale
NAME
scale() - apply a scaling to a transformation matrix
SYNOPSIS
float *scale(float *matrix, float x, float y, float z)
DESCRIPTION
Post-multiplies the 4x4 transformation `matrix` (a 16-element flat
array of floats, as produced by id_matrix()) by a scaling of
(`x`, `y`, `z`), computing `matrix` = `matrix` * scaling.
The passed `matrix` array is modified IN PLACE: its 16 elements are
overwritten with the result, and that same array is left on the stack
as the return value. scale() mutates its first argument; the return
value is the very array you passed in, not a copy.
