src/core/window.c: Override window's depth and xvisual only if window size is not 1x1.

Fixes issue with using BLIT and VSYNC breakage in case OBS Studio or any other screen recording software works, real reason of issue is `window->depth = attrs->depth` was used in case window size is `1x1`, but just in case I also included `window->xvisual = attrs->visual` to be overriden only if window size is not `1x1`.
