This also reverts commit 2b52dd84:
wordpad: Empty the richedit undo buffer on creation.

The reverted commit I created to fix an issue that only applied to Wine,
but it just masked the issue which was in richedit controls.  The
default character format was set in two places while wordpad was
starting up, and caused wordpad to have two undo items at startup.

Trying to set the font size to a value larger than 1638
in points (yHeightCharPtsMost) using EM_SETCHARFORMAT will cause it to be
set to actually set to the maximum.

rpcrt4: Implement MesEncodeIncrementalHandleCreate, MesDecodeIncrementalHandleCreate, MesIncrementalHandleReset and MesHandleFree.

This creates an nvts version of this function, and removes the nvts
code from the original one. The nvts version is used by the nvts
pipeline implementation, the original one by the nvrc-only, atifs and
ffp one.

As long as we have the shader constants in misc, it is best to keep
all the code that affects shader constants, like bumpenvmat setting,
in there as well.
