-------------------------------------------------+-------------------------
This patch series abolishes automatic resizing of the minimap, which is
desirable for a configuration option to change the default radar size, to
be introduced with #4629.
Radar size ranges from 8 to 64 with a default value is 16 (see
'./src/radar.h').
A routine that assumed a value < 4 has been removed.
Maps with width < 150 tiles like Sk-Rush no longer start with a resized
radar of 14 (if the screen is <= 640 pixels wide) or 32, which will likely
be noticed by users (see attached image [raw-
attachment:minimap_size_comparison.png]).
Almost every single one of the popular 8-player NTW maps is 140 tiles wide
and will thus start with a smaller radar size. Among 680 different maps
whose size was measured with a bash script (view [raw-
attachment:list_map_sizes] for the script and [raw-
attachment:map_sizes.csv] for the results), 36% were affected overall.
When rotateRadar was enabled, all minimaps were rescaled as though their
larger side (either width or height) was 128 tiles long.
A map 143x159 tiles large (the average dimensions of 680 maps examined)
would thus appear with a sidelength reduced by about ~ 20%. Note that maps
cannot be larger than 256 tiles or smaller than 2 tiles on either side,
although tiny maps are rare: the smallest popular multiplayer map,
HugeassRebuild, is 21x21 tiles in size and thus appeared with a sidelength
about 6-times larger with rotating radar than fixed radar (see attached
image [raw-attachment:radar_rotation_enlarging_minimap.png]).
Rotating radar also shifted the center of the minimap so that it fit into
a square of its largest sidelength (see attached image [raw-
attachment:radar_rotation_centering_minimap.png]).
This cost valuable screen space: Out of 680 maps, 45% were higher than
wide and would thus move to the left, 14% were wider than high and shifted
upwards, while 40% had equal dimensions and thereby unaffected.
Lastly, the radar size in tutorials has also increased since a routine
shrinking it was ignored when converting them to JavaScript (ticket #4641)
and removed from the game altogether with
76ac44c84b7f89a860c743202bb002586d137e63.
