This enables smooth resizing of the window using a
fixed aspect ratio, instead of snapping into the

events delivered during the resize operation
(whereas SDL_PollEvent blocks until done on macOS).

No need to create a new texture for every
rendered frame, unless the scaling method

player interface to GPU memory repeatedly.
+ Remove unused lcd_display_redraw &
having_new_lcd variables
