// signed char ImS8; // 8-bit signed integer
// unsigned char ImU8; // 8-bit unsigned integer
// signed short ImS16; // 16-bit signed integer
// unsigned short ImU16; // 16-bit unsigned integer
// signed int ImS32; // 32-bit signed integer == int
// unsigned int ImU32; // 32-bit unsigned integer
// signed long long ImS64; // 64-bit signed integer
// unsigned long long ImU64; // 64-bit unsigned integer
// (note: this list does *not* include `long`, `unsigned long` and `long double`)
//
// You can customize the supported types by defining IMPLOT_CUSTOM_NUMERIC_TYPES at compile time to define your own type list.
// As an example, you could use the compile time define given by the line below in order to support only float and double.
// -DIMPLOT_CUSTOM_NUMERIC_TYPES="(float)(double)"
// In order to support all known C++ types, use:
// -DIMPLOT_CUSTOM_NUMERIC_TYPES="(signed char)(unsigned char)(signed short)(unsigned short)(signed int)(unsigned int)(signed long)(unsigned long)(signed long long)(unsigned long long)(float)(double)(long double)"
