tigr window creation can hang

[zlago]

creating a window with width and height set to 0 makes the process hang (?)

doing that and also setting mode to AUTO causes an X error to appear

expected behaviour: one of

• window is created but hidden
• window fails to create

system: gnu/linux

minimal sample for reproducing:

#include "tigr.h"
int main(void) {
	tigrWindow(0, 0, 0, 0);
}
