Enrico Weigelt, metux IT consult 53876f1ef1 randr: fix RRGetCrtcTransform reply length, part 2
Mixed up reply vs request. Obviously, the size substracted from reply
struct's one has to be the one of the generic reply, not generic requst :o

Background: the meaning of the length field isn't entirely intuitive.

a) the size is in 4-byte units, instead of bytes (therefore passing through
   bytes_to_int32() call)
b) it's not the total packet size, but only the *extra* payload size, ergo:
   how much is the packet longer than a xGenericReply = 8 units = 32 bytes.
   (min. packet size is 32 bytes -> length = 0)

In order to prevent those kind of coding errors ever happening again, it might
be a good idea putting that into a generic macro.

No need to go indirectly through a vector table, since everything's fixed
anyways. It's not a pretty robust programming style: any changes need great
care, in order to not mix up things.

Replacing this by direct switch/case statement, which is using the defines
from the xrandr protocol headers. Also adding a little bit more protection
against subtle programming errors and reducing cognitive load (source size)
on understanding the code by using a tiny macro for deducing define name and
function name from the request's name.

This approach actually uncovered some subtle bug that had been waiting in
the dark for over 15 years.

As collateral benefit, getting a tiny bit better performance.
