The Rebirth main screen grd_curscreen borrows the memory allocated by
SDL_CreateRGBSurface to store its data. Store the pointer to that
surface inside grd_curscreen and make grd_curscreen responsible for
freeing the surface.
clang-14 on OSX, but not clang-14 on x86_64-pc-linux-gnu, fails
class template argument deduction when given:
```
char *c1 = initializer();
const char *c2 = c1 + 1;
std::span{c1, c2};
```
clang correctly refuses to match this to `std::span(pointer, pointer)`,
but fails to find the constructor `std::span(iterator, sentinel)`.
Work around this by changing the type of the sentinel from
`const uint8_t *` to `color_palette_index *` (an alias of `uint8_t *`).

This started out as underline, but one of the special drawing modes uses
it to draw an underline-width block across the entire vertical height of
the character.
Most callers do not need it, and it is only vaguely related to the
purpose of measuring a particular string. For those callers that need
it, lift it out.
- Inline add_computed_color into gr_find_closest_color, and then only
one function will need access to Computed_colors.
- Allow the recent-choice bubble-up logic to apply to all elements
- If all entries are in use, always overwrite the last element in
Computed_colors instead of picking one randomly.
gr_find_closest_color did not need it. Remove it. For the others,
resetting the count is sufficient. There is no need to reset the
individual elements.
A prior conversion changed the actual rendering to use the argument
cv_font, but still picked which render function to use based on the
flags for the active font. Switch to use only the supplied font.
Previously, if the background failed to load, the kmatrix window was
immediately aborted. Change the logic so that a failure to load uses a
blank black background, but still shows the kmatrix window.
lengthof was added to provide the size of C arrays. C++17 std::size is
now available, and can serve the same purpose. Remove the custom
lengthof.
The generated code is the same in both cases, other than the change in
line numbers caused by removal of the #include directives.
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.
