Introduce read{RTI13,RTI1516,RTI1516E}ObjectModelTemplate
methods. Deprecate the current readObjectModelTemplate method
and provide a short term upgrade path.
executing the fgcommand loadxml implicitely untied every previously
tied property if a property type was given in the property element.
That made it impossible to autosave aircraft data for tied properties.
This patch should fix this. It adds an inconsitency, though:
if a property with a given type is read in which has been tied to
before and the property types do not match, the property type in the
xml file will be ignored.
Fixes the more basic probelm of "SGModelLib::findDataFile" resolving an
empty file name to the fgdata (directory) path. findData_File_ should
never return a _directory_ path, only valid _file_ names.
Don't resolve the empty file name, which would result in the fgdata
directory path (instead of a path to a file). Eventually this resulted in
a segfault, partly due to a bug in "osgDB::readImageFile", which reports
"success" when given a directory (instead of a file) path, though it
doesn't return a valid image object.
Since the message should help people doing textures to
provide texture files that run everywhere, do not omit
the messages just because the build platform did not
know these.
Print a descriptive warning on images that are given
in a texture format that do only work in presence of an
extension that might not be there at runtime.
Cut trailing separators when converting from string to sgpath.
Also, SGPath::fix does NOT replace ":". It only replaces "\" with "/",
so the "i!=1" check for Windows made no sense (rule #9: never believe
a source code comment).
This fixes a problem with fonts no longer being correctly
loaded as a side effect of the spt meta object loader.
The readObject slot is obviously being called for several
unrelated file extensions. To make sure the search continues,
osgDB::ReaderWriter::ReadResult::FILE_NOT_HANDLED needs to
be returned in this case.
