One thing I noticed when I wrote my compiler was that a float1x1 is not the
same as a float1 or float. I did not implement this difference nor do I know
if any games depend on it.
(That's no reason to hold up this patch, just something to keep in mind for
further work)
Yeah, I noticed that too, but it doesn't seem to make much of a
difference in practice. Of course, if later on it shows that it
actually matters for something relevant, I'll change things
accordingly.
For the effect interface, it makes a difference. See
http://source.winehq.org/git/wine.git/blob/90f93e3819dcaa0cea16bd297fa69a359fb6b517:/dlls/d3dx9_36/tests/effect.c#l320
and
http://source.winehq.org/git/wine.git/blob/90f93e3819dcaa0cea16bd297fa69a359fb6b517:/dlls/d3dx9_36/tests/effect.c#l501
. The difference is the type D3DXPC_SCALAR vs D3DXPC_VECTOR vs
D3DXPC_MATRIX_ROWS and of course some different handling, see
http://source.winehq.org/git/wine.git/blob/90f93e3819dcaa0cea16bd297fa69a359fb6b517:/dlls/d3dx9_36/tests/effect.c#l1191
. A test may help to check how variables in shaders are handled.
