Enum gbm_sys::gbm_bo_transfer_flags

#[repr(u32)]
pub enum gbm_bo_transfer_flags {
    GBM_BO_TRANSFER_READ,
    GBM_BO_TRANSFER_WRITE,
    GBM_BO_TRANSFER_READ_WRITE,
}

Flags to indicate the type of mapping for the buffer - these are passed into gbm_bo_map(). The caller must set the union of all the flags that are appropriate.

These flags are independent of the GBM_BO_USE_* creation flags. However, mapping the buffer may require copying to/from a staging buffer.
