widl: Pass the actual type into check_remoting_fields and check_field_common instead of the type name.

uxtheme: Speed up UXTHEME_SizedBlt in the ST_TILE by building an appropriately-sized memory bitmap out of the tile instead of iterating with UXTHEME_Blt() directly.

riched32: Implement a portion of suggested interpretation of CRLF handling for richedit 1.0 emulation.

Fixes a few todos introduced by previous patch.
