Subject: user term default fg/bg now accessible as fg or bg color with -1
X-Git-Tag: 1.6.1-roc-2606C^2~2
X-Git-Url: https://skyeroc.xyz/gitweb/?a=commitdiff_plain;h=90e8d728a23ad21796c72a1d41f2c9cc518fc89d;p=dgamelaunch

user term default fg/bg now accessible as fg or bg color with -1

* Improve explanatory comment

* Flatten another if statement

* Add default-color pairs (129-152)

* Refactor remap_attr_string

* Make default colors more accessible
* Stop trying to overwrite color 0
* let remap_attr_string() read negative numbers
* parse negative numbers to return default-pairs

* Stop reducing screen height by 3 for banners
