This patch exports all symbols required by the compilable
(in a x86 linux computer) xorg/driver/* modules.
Still missing symbols worth mentioning are:
sunleo
miFindMaxBand no longer available
intel (uxa/uxa-accel.c)
fbShmPutImage no longer available (and should have been static)
mga
MGAGetClientPointer (should come from matrox's libhal)
This is not a definitive "visibility" patch, as all it does is to
export missing symbols, but the modules that current don't compile,
may require more symbols once fixed, and third party drivers should
also require more symbols exported.
A "definitive" patch should export symbols defined in the sdk.
../../../../hw/xfree86/xaa/xaaTables.c:9:14: warning: symbol 'byte_expand3' was not declared. Should it be static?
../../../../hw/xfree86/xaa/xaaTables.c:53:14: warning: symbol 'byte_reversed_expand3' was not declared. Should it be static?
The patch removes all macros in the format
define xf86_sym ((type (*)(argument-list))LoaderSymbol("sym"))
creates a new macro in the format
define xf86_sym sym
and ensures "sym" is a "visible" symbol.
The patch doesn't add or remove features, and is source and binary
compatible with previous shared objects (with the difference that it
requires the dlloader).
These symbols are a special case, as, due to the fact that LoaderSymbol
was being used to reference them, they are not easily found by "automated"
tools that check for missing symbols. And now it also have the benefit
that the compiler/loader "knows what is going on".
pixman 0.13.2 now holds all of the matrix operations. This leaves
the protocol conversion routines and some ABI stubs in place

Doing projective transforms required repositioning the cursor using the
hotspot, but that requires relocating the upper left corner in terms of said
hotspot.
Instead of using a separate function to notify DIX about transform changes,
add the transform to RRCrtcNotify so that the whole Crtc state changes
atomically.
RandR matrix computations lose too much precision in fixed point;
computations using the inverted matrix can be as much as 10 pixels off.
Convert them to double precision values and pass those around. These API
changes are fairly heavyweight; the official Render interface remains fixed
point, so the fixed point matrix comes along for the ride everywhere.
Add APIs to xf86RandR12 support and randr extension to record whether the
driver supports transforms, report that value in the RRGetCrtcTransform
reply.
