Cool glad to see that these requirements can be relaxed without any major
issue. While we are it, I have a proposal that would make C bindings a bit less
cumbersome. So nim sets can't be casted to C bitflags, because the enums are
converted to powers of two automatically. But if there was a .flagbits pragma
for enums that could influence how sets are made from this enum, that would
guarantee full compatibility with C bitflags. Think about it people!
type
VkAccessFlagBits* {.size: sizeof(int32), flagbits.} = enum
IndirectCommandReadBit = 1
IndexReadBit
VertexAttributeReadBit = 4
UniformReadBit = 8
InputAttachmentReadBit = 16

ShaderWriteBit = 64
ColorAttachmentReadBit = 128

MemoryReadBit = 32768
MemoryWriteBit = 65536
VkAccessFlags* {.size: sizeof(uint32) = set[VkAccessFlagBits]
