Device and Queue in an Arc? 
Arc<Queue> and never have to ask for it again.
so far, I haven't used Arcs, but am starting to think that using them would reduce the amount of function parameters everywhere and improve my sanity a little
now in my texture storage, I find that I'll need to create many bind groups (I think descriptor sets in vulkan) for each new texture. either when the texture is newly added or live during rendering.
however, each bind group will also need to contain an entry for both the sampler and the gpu camera buffer. both of those would also just work fine in an Arc, since pretty much everything gpu-related only need immutable references. so basically I'm currently thinking about throwing around Arcs and wondering if that is commonly done ^^

void main()
{
FragColor = mix(texture(texture0, TexCoord), texture(texture1, TexCoord), 0.2);
// FragColor = texture(texture1, TexCoord);
}glBindSampler it uses glUniform1i
1glBindSampler it uses glUniform1i glBindSampler it uses glUniform1i 
? ? ? 
glGetUniformLocation(prog, "texture1") returns something that makes sense
void main()
{
FragColor = mix(texture(texture0, TexCoord), texture(texture1, TexCoord), 0.2);
// FragColor = texture(texture1, TexCoord);
}
