Pierre Wendling 95f6edb9a5 Test: Refactor trigonometric tests into a helper. 
The precision test of these functions need a special helper, it can also
be used for their arc functions down the line.

gets truncated instead of casted to signed int64.

Pierre Wendling 43c22e5d1e Test: Refactor math suite duplicate code. 
Many tests were using the same underlying routine, as such three helper
functions were added:
- A wrapper to test double -> double functions.
- A wrapper to test (double, double) -> double functions,
- A wrapper for range tests on double -> double functions.

Simon McVittie 38ef678990 test: Add a `make install` target for the tests 
This makes it more convenient to compile them alongside SDL, install
them in an optional package and use them as smoke-tests or diagnostic
tools. The default installation directory is taken from GNOME's
installed-tests, which seems as good a convention as any other:

Simon McVittie 76a7b629bf test: Add some common code to load test resources 
As well as reducing duplication, this lets the tests load their resources
from the SDL_GetBasePath() on platforms that support it, which is useful
if the tests are compiled along with the rest of SDL and installed below
/usr as manual tests, similar to GNOME's installed-tests convention.

Simon McVittie b4256d03e9 testevdev: Adapt to a broader definition of keyboards 
At the time I contributed this unit test, SDL had a relatively narrow
definition of what is a keyboard, approximately matching udev
ID_INPUT_KEYBOARD. Now it uses the equivalent of udev ID_INPUT_KEY,
which matches anything with keyboard keys, and not just reasonably
complete alphanumeric keyboards.

This file uses internal SDL headers as a hack, without actually being built as part of SDL, so we should use normal C functions here.

Misa 3bf7994fe2 Add and use `SDL_FALLTHROUGH` for fallthroughs 
Case fallthrough warnings can be suppressed using the __fallthrough__
compiler attribute. Unfortunately, not all compilers have this
attribute, or even have __has_attribute to check if they have the
__fallthrough__ attribute. [[fallthrough]] is also available in C++17
and the next C2x, but not everyone uses C++17 or C2x.

So define the SDL_FALLTHROUGH macro to deal with those problems - if we
are using C++17 or C2x, it expands to [[fallthrough]]; else if the
compiler has __has_attribute and has the __fallthrough__ attribute, then
it expands to __attribute__((__fallthrough__)); else it expands to an
empty statement, with a /* fallthrough */ comment (it's a do {} while
(0) statement, because users of this macro need to use a semicolon,
because [[fallthrough]] and __attribute__((__fallthrough__)) require a
semicolon).

Clang before Clang 10 and GCC before GCC 7 have problems with using
__attribute__ as a sole statement and warn about a "declaration not
declaring anything", so fall back to using the /* fallthrough */ comment
if we are using those older compiler versions.

Applications using SDL are also free to use this macro (because it is
defined in begin_code.h).

All existing /* fallthrough */ comments have been replaced with this
macro. Some of them were unnecessary because they were the last case in
a switch; using SDL_FALLTHROUGH in those cases would result in a compile
error on compilers that support __fallthrough__, for having a
__attribute__((__fallthrough__)) statement that didn't immediately
precede a case label.

testwm2: Fix video modes menu hit detection when highdpi or logical size used (#4936) 
* SDLTest_CommonDrawWindowInfo: log SDL_RenderGetScale, SDL_RenderGetLogicalSize

* testwm2: fix video modes menu hit detection in High DPI cases

- also when logical size is specified, e.g.
  `--logical 640x480 --resizable --allow-highdpi`

* add function to determine logical coordinates of renderer point when given window point

* change since to the targeted milestone

* fix typo

* rename for consistency

* Change logical coordinate type to float, since we can render with floating point precision.

* add function to convert logical to window coordinates

* testwm2: use new SDL_RenderWindowToLogical

* SDL_render.c: alternate SDL_RenderWindowToLogical/SDL_RenderLogicalToWindow
