31 VRAM. First, the base address retrieved through GetPixBaseAddr or

33 memory is allocated in VRAM. This can occur either by explicit
74212992fb08 Initial revision
Sam Lantinga <slouken@lokigames.com>
parents:

34 allocations, such as calls to NewGWorld, or by implicit ones, such as
74212992fb08 Initial revision
Sam Lantinga <slouken@lokigames.com>

38 You should never store an image's base address for longer than is
