TTF_WasInit - Check if SDL_ttf is initialized.

       This function is available since SDL_ttf 3.0.0.

       This  reports  the  number  of times the library has been initialized by a call to TTF_Init (), without a
       paired deinitialization request from

       TTF_Quit ().

       In short: if it's greater than zero, the library is currently initialized and ready to work. If zero,  it
       is not initialized.

       Despite the return value being a signed integer, this function should not return a negative number.

       Defined in SDL3_ttf/SDL_ttf.h

       TTF_WasInit - Check if SDL_ttf is initialized.

       Returns  the  current  number  of  initialization calls, that need to eventually be paired with this many
       calls to TTF_Quit ().
