Add an inclusion of <SDL.h> since, for Windows targets, this triggers a
chain of includes that leads to <intrin.h>, which causes
-Wredundant-decls to print a diagnostic. This allows Windows targets to
declare -Wredundant-decls as unusable, while enabling it for non-Windows
targets.
This fixes PCX loading in the non-editor build. PCX loading broke in
3114874713 because it switched from PHYSFSX_openReadBuffered to a call
which did not handle the presence of the marker byte in the filename.
The from_hog_only flag has not been properly supported since the
introduction of PHYSFSX_openReadBuffered in
8b323e7214. Editor builds ignored it on
purpose, and non-editor builds pretended to respect it, only to then
ignore it down inside PHYSFSX_openReadBuffered. For consistency with
code paths that do not use PHYSFSX_openReadBuffered, disable the bypass
in PHYSFSX_openReadBuffered and remove the code in show_title_screen
that applied the flag.

The automap code keeps a mostly-private secondary copy of control_info.
The change to reset control_info before the event loop reset the main
copy of control_info for the automap, not the copy that the automap
actually used. Fix this by passing the desired control_info to relevant
functions instead of always using the global variable Controls.

This field is used in the SDL build for rendering. In the GL build, its
only purpose is for the editor to write it to a PIG file. Change that
one use to compute the value as needed. Move all other references
behind a preprocessor test for !DXX_USE_OGL. This shrinks the size of
grs_bitmap by 1 pointer, since the compiler added padding after
avg_color up to the size of the next aligned pointer.
gcc has a special case to devolve to memset if both the pointed-at data
and the value to fill are considered a byte. All uses of
DXX_POISON_MEMORY pass a value that fits in a byte, so change the
signature to be a byte, to encourage gcc to activate the special case.
This adds a new dependency, but most systems likely already have
SDL_image installed. Use of SDL_image can be disabled, but this is
discouraged, because various in-game interfaces assume the use of the
original background.
The old implementation automatically corrected for filename case. The
new implementation expects that the supplied filename can be passed to
PYHSFS_openRead as-is. All known uses in-game have been corrected to
satisfy this requirement. If the new stricter match requirement becomes
a problem, a variant of PHYSFSRWOPS_openRead that adjusts filename case
could be created for use here.

gcc-10 warns that the game information text may be truncated, because it
overestimates the maximum possible length of some strings. Handle the
warning by changing the format string to explicitly truncate these
strings at their maximum legal lengths.
gcc-10 warns that if immediate_directories were very large, the sprintf
result would be truncated. This is true, but a user is extremely
unlikely to have enough directories to trigger this code path. Handle
the warning by explicitly returning an empty string if truncation would
otherwise occur. This is not strictly correct, but it can be handled
with very little code, eliminates the warning, and is unlikely to matter
in practice.
As reported in pull #507, the D1 implementation of the reduction was
incorrect and never reduced laser power. Therefore, when D2 emulates
D1, D2 should emulate the effect of the bug, by not reducing laser
power.
The code that provides the 0.75x multiplier to laser bolts when they're fired
using the quad laser is present in D1 as in D2, however it is incorrect and
results in it not being applied. As such, it is more accurate to exclude the
multiplier when compiling D1.
Thanks to SaladBadger for the tip.
Commit 2bcc7bb371 restricted
Laser_create_new to only create lasers for known weapon types. This
seemed like a good idea, but broke custom levels that use undocumented
laser types. It also replaced logic that coerced invalid weapon numbers
into a type 1 laser with logic that prevented firing such weapons at
all. This rendered robots with unknown or broken weapon data unable to
fire.
Commit 0c30fa7cf3 relaxed the logic to
prevent firing only in editor builds, but allow firing unknown or
invalid weapon types in release builds. Firing unknown weapon types may
work. Firing invalid weapon types may cause the game to crash when data
is accessed beyond the end of the defined weapon data. This caused the
crash reported in issue #506.
Revert to the 0.58.1 rule that invalid weapons are coerced to be a
player level 1 laser. Add a diagnostic when such a weapon is fired,
since the level author should have requested that weapon explicitly if
that was intended.
