Volume control and mute

Hi.

It would be nice an option to control the volume and/or mute it.

Thanks!

"OpenGL texture binding not supported"

On a Windows machine (specific OS and hardware seems to be irrelevant) this project will not compile firstly due some missing lib files from the rust library which I documented a workaround for here . After this issue is fixed, the project will run on a Linux machine but on a Windows platform when it attempts to bind textures it will panic with the error message mentioned in the title.

The panic occurs as a result of a call to sys::render::SDL::_GL_BindTexture(... , ...) on line 1500 of render.rs. I'm currently working on figuring out exactly what the error is. Based on some snooping though it appears that this function is known to be problematic and is likely a Windows only error.

Inside of gate this exception is thrown in gate/src/core/sdl/mod.rs at line 117 on the call to the function. I think the Linux implementation might just ignore the error message which could explain why this only works on Linux.

sdl2_image.lib not found

am a beginner to rust and git so pls bear with me. I tried to compile with eclipse but the below error is encountered.
this is the error=>
