Błażej Szczygieł a62f1d0356 xcb: Prevent shared memory allocation on every window resize
Allocate new shared memory only when window size grows or when window
size is 2 times smaller than allocated memory size. This improves
window resizing performance and also allows to free some memory if
window becames much smaller.
