Ditto. I should note that fixing the fvf -> decl conversion seems rather 
important, because the FVF loading code will not work with a vertex 
shader at the moment - as far as I can see this will break 3 more demos, 
so that brings the count of broken demos up to 5 (ASCII, Sketch, 
RollerCoaster, dx9_hlsl_* (2) ). Those demos will set a shader, and then 
call SetFVF() afterwards (but primitiveConvertToStridedData will see 
that shader != NULL and will not do anything)

The current code has 2 routines - primitiveConvertToStridedData (for 
FVF) and primitiveDeclarationConvertToStridedData (for declaration). It 
seems as if the FVF should just be converted to a declaration when it is 
set, and a single function should be used afterwards. I could be wrong 
though, haven't looked at this in great detail yet...
