use libc types
I should probably define the constants as the c_ulong type, to enable compilation on both 64 and 32 bit systems.

ioctl return -1 when running rust logo example using kdMode::Graphics
When I run the rust-logo example, it failed with this error message:

I knows only a little about fbdev and IDW why the problem occurs and how to fix it. Much appreciate if you could help :)
FrameBuffer::new should not take a &str argument
Instead should take AsRef<Path>.
This should be a backwards compatible change.
Without this, I have to convert my path to a &str before giving it to the function.
Same concept is implemented in std::fs::File::open.
Implement Debug for Framebuffer
Is there a reason for the Framebuffer struct to not implement the Debug trait? I want to store a Framebuffer inside a struct which implements Debug, but this results in an error. I don't think I can implement this trait on Framebuffer in my own project.
I checked the File and Mmap structs which Framebuffer uses and they both implement Debug, so there should not be an issue to do the same for Framebuffer, right?
I need your help
Apparently the values in var_screen_info and fix_screen_info differ among drivers. Could you please post the driver you are using and the debug output from the two structs?
let fb = Framebuffer::new("/dev/fb0");
println!("{:?} {:?}", fb.var_screen_info, fb.fix_screen_info);
Thanks!

Starfield demo could crash with divide by zero
Line 87 of starfield/main.rs sets self.x to a random float between -wh and wh which could include the value 0. Line 89 divides self.b by that number, which could result in a divide by zero.
Display Example output on README
Hi,
I don't have required rust configuration on my current computer, so i can't execute examples given for this library.
Can you show what the output would looks like?

Errors when trying to cross compile to ARM
Compiling on a x86 computer for an arm target :
cargo build --release --example rust-logo --target arm-unknown-linux-gnueabi
The error is :
# ./rust-logo
./rust-logo: /lib/libc.so.6: version `GLIBC_2.28' not found (required by ./rust-logo)
./rust-logo: /lib/libc.so.6: version `GLIBC_2.18' not found (required by ./rust-logo)
./rust-logo: /lib/libc.so.6: version `GLIBC_2.33' not found (required by ./rust-logo)
./rust-logo: /lib/libc.so.6: version `GLIBC_2.32' not found (required by ./rust-logo)
./rust-logo: /lib/libc.so.6: version `GLIBC_2.34' not found (required by ./rust-logo)
This is because the target linux system is an "old" linux which I can't upgrade : https://linux-sunxi.org/Bookeen_Cybook_Muse
I tried to build with musleabi to avoid the dependency on libc6 :
cargo build --release --example rust-logo --target armv7-unknown-linux-musleabi
with config :
cat ~/.cargo/config.toml
[target.armv7-unknown-linux-musleabi]
linker = "/home/arthur/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/lib/rustlib/x86_64-unknown-linux-gnu/bin/rust-lld"
This works for a "Hello World" rust binary, but doesn't for rust-framebuffer :
The result is :
# ./rust-logo
thread 'main' panicked at examples/rust-logo/main.rs:15:61:
called `Result::unwrap()` on an `Err` value: BmpError { kind: BmpIoError(Os { code: 2, kind: NotFound, message: "No such file or directory" }), details: "BMP Error: Io Error" }
