oleaut32: Don't call SafeArrayAllocData in LPSAFEARRAY_UserUnmarshal if we called SafeArrayCreateEx instead of SafeArrayAllocDescriptor.

Otherwise, we'll leak memory.

The GL_ARB_vertex_program extension does not define a standard value for
output texture coordinates. This makes problems when using vertex
shaders with fixed function fragment processing because fffp divides the
texture coords by its .w component. This means that gl shaders have to
write to the .w component of texture coords. Direct3D shaders however
do not.

ddraw: Rename DDRAW_dump_flags_() to DDRAW_dump_flags_nolf() to clarify its difference from DDRAW_dump_flags().

user32/tests: Pass HEAP_ZERO_MEMORY to HeapAlloc() instead of clearing the memory with a separate memset() call.
