[WIN32SS][NTGDI] Registry-based font management (#1816)
CORE-16269 - Add IntGdiAddFontResourceEx function that is extended from IntGdiAddFontResource, in order to add dwFlags parameter. - Add IntLoadFontsInRegistry function that will load the fonts from registry info. - If loading from registry failed, IntLoadSystemFonts will be called. - Use IntLoadFontsInRegistry rather than IntLoadSystemFonts in the OS startup. - Add NameFromCharSet function. - Append " (CharSetName)" to registry value name if not TrueType. --- win32ss/gdi/ntgdi/font.h | 1 + win32ss/gdi/ntgdi/freetype.c | 267 +++++++++++++++++++++++++++++++++++++++++-- win32ss/gdi/ntgdi/text.h | 6 + 3 files changed, 264 insertions(+), 10 deletions(-)
