Crtc offsets are in screen space, not crtc space, and hence should be
applied relative to the screen->crtc transform, not the crtc->transform.
This fix was found in the 'cherry pick' of 62fc98c on server-1.6-branch,
clearly some new definition of 'cherry pick' that I am unaware of.

The matrix computation for rotation and reflection resulted in dropping a
row or column of pixels as the offsets used in the matrix computations used
width and height rather than width-1 and height-1.

If the computation of the composite fixed-point transform for RandR
overflows at any point, take the resulting floating point transform and
scale that back to fit in a fixed point matrix. This ensures that a matrix
will always be available, although perhaps at reduced precision. Someday we
should add floating point matrices to Render.

Save in a few special cases, _X_EXPORT should not be used in C source
files. Instead, it should be used in headers, and the proper C source
include that header. Some special cases are symbols that need to be
shared between modules, but not expected to be used by external drivers,
and symbols that are accessible via LoaderSymbol/dlopen.
This patch also adds conditionally some new sdk header files, depending
on extensions enabled. These files were added to match pattern for
other extensions/modules, that is, have the headers "deciding" symbol
visibility in the sdk. These headers are:
o Xext/panoramiXsrv.h, Xext/panoramiX.h
o fbpict.h (unconditionally)
o vidmodeproc.h
o mioverlay.h (unconditionally, used only by xaa)
o xfixes.h (unconditionally, symbols required by dri2)
LoaderSymbol and similar functions now don't have different prototypes,
in loaderProcs.h and xf86Module.h, so that both headers can be included,
without the need of defining IN_LOADER.
xf86NewInputDevice() device prototype readded to xf86Xinput.h, but
not exported (and with a comment about it).
This is the biggest "visibility" patch. Instead of doing a "export"
symbol on demand, export everything in the sdk, so that if some module
fails due to an unresolved symbol, it is because it is using a symbol
not in the sdk.
Most exported symbols shouldn't really be made visible, neither
advertised in the sdk, as they are only used by a single shared object.
Symbols in the sdk (or referenced in sdk macros), but not defined
anywhere include:

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.
