2f3883b126a405f92b19e829472f614c7352b4f9vboxsync * We have to make sure we're going to generate unique texture IDs.
2f3883b126a405f92b19e829472f614c7352b4f9vboxsync * That wasn't the case before snapshot loading, because we could just rely on host video drivers.
5f2b03bf7695dabd71222dba123532a3f76828c1vboxsync * Now we could have a set of loaded texture IDs which aren't already reserved in the host driver.
2f3883b126a405f92b19e829472f614c7352b4f9vboxsync * Note: It seems, that it's easy to reserve ATI/NVidia IDs, by simply calling glGenTextures
2f3883b126a405f92b19e829472f614c7352b4f9vboxsync * with n==number of loaded textures. But it's really implementation dependant. So can't rely that it'll not change.
