Using the SalColor->CGFloat[] helper gets more of VCL into the scope
which causes conflicting declarations between css::awt and vcl-classic
font attributes so their namespace must be explicitly qualified

According to http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7078419
JDK 7 and up will never support classfile formats 48 or earlier because
they lack generic signature attributes. Our current baseline is JDK 5
anyway which has the classfile format 49
(see e.g. http://en.wikipedia.org/wiki/Java_class_file or the JVM spec)

#121625# - method <ExtensionManager::getExtensionsWithSameId(..)> - catch certain exceptions to avoid crashes

- method <ExtensionManager::getAllExtensions(..)> - do not add bundled extensions twice to the map; the map can not hold a fourth entry.

std::ifstream's EOF bit is not something to be worry about
when the preceding operation was reading to the EOF

Patch by: Tsutomu Uchino

Clang has had problems with braced string literals of unsigned chars
(http://llvm.org/viewvc/llvm-project?revision=154756&view=revision)
so we have to avoid them if we need to compile with such versions

"data_" is an actual data pointer but "data" is a member function
(since vigra-1.4). The method resizeCopy() seems to confuse data and data_
which the clang compiler was happy to point out. The OOo patch to vigra-1.4
already solved that problem but it was lost in the upgrade to vigra-1.6

Workaround the issue for now.
