* Machine dependent values:

* GLYPHPADBYTES should be chosen with consideration for the space-time
|

|
|
|
|
* in the font bitmaps (both on disk and in memory), but that access of
|
|
|
|
* the bitmaps will cause odd-address memory references. Padding to
|
|

|
* 2 bytes would ensure even address memory references and would
|
|
|
|
* be suitable for a 68010-class machine, but at the expense of wasted
|
|
|
|
* space in the font bitmaps. Padding to 4 bytes would be good
|
|
|
|
* for real 32 bit machines, etc. Be sure that you tell the font
|
|
|
|
* compiler what kind of padding you want because its defines are
|
|
|
|
* kept separate from this. See server/include/font.h for how
|

Rework symbol visibility for easier maintenance
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).
