After discussion with @ocornut, SDL_RenderGeometryRaw() will take floating point colors and conversion from 8-bit color can happen on the application side. We can always add an 8-bit color fast path in the future if we need it on handheld platforms.
If you need code to do this in your application, you can use the following:
int SDL_RenderGeometryRaw8BitColor(SDL_Renderer *renderer, SDL_Texture *texture, const float *xy, int xy_stride, const SDL_Color *color, int color_stride, const float *uv, int uv_stride, int num_vertices, const void *indices, int num_indices, int size_indices)
{
int i, retval, isstack;
const Uint8 *color2 = (const Uint8 *)color;
SDL_FColor *color3;
if (num_vertices <= 0) {
return SDL_InvalidParamError("num_vertices");
}
if (!color) {
return SDL_InvalidParamError("color");
}
color3 = (SDL_FColor *)SDL_small_alloc(SDL_FColor, num_vertices, &isstack);
if (!color3) {
return -1;
}
for (i = 0; i < num_vertices; ++i) {
color3[i].r = color->r / 255.0f;
color3[i].g = color->g / 255.0f;
color3[i].b = color->b / 255.0f;
color3[i].a = color->a / 255.0f;
color2 += color_stride;
color = (const SDL_Color *)color2;
}
retval = SDL_RenderGeometryRaw(renderer, texture, xy, xy_stride, color3, sizeof(*color3), uv, uv_stride, num_vertices, indices, num_indices, size_indices);
SDL_small_free(color3, isstack);
return retval;
}

The new function includes the cursor position so IME UI elements can be placed relative to the cursor, as well as having the whole text area available so on-screen keyboards can avoid it.
This code already handled NULL fine, it just got wrapped in a SDL_strdup call
in e23257307e220c7dd3d827e195f52adaabaaeeeb, so make that SDL_strdup check for
NULL first.
SDL_StartTextInput(), SDL_StopTextInput(), SDL_TextInputActive(), SDL_ClearComposition(), and SDL_SetTextInputRect() all now take a window parameter.
This change also fixes IME candidate positioning when SDL_SetTextInputRect() is called before SDL_StartTextInput(), as is recommended in the documentation.
This is how these globals were intended to have been used, similar to
what we already did for the Fanatec device.

This is an out-of-tree driver providing an alternative interface to
X-Box gamepads. Compared with the in-kernel driver, it adds four
pseudo-buttons used to indicate which profile is active, and an
optional "misc" axis that combines the two triggers into a rudder.
Partially addresses libsdl-org/SDL#7823

For some devices, such as the Steam Deck's built-in Steam Controller,
the version number reported via evdev and the version number reported
via USB are different. We don't currently use this information anyway,
but in case we want to use it in the future, let's include it in our
test data.
