* builds/win32/visualc/freetype.vcproj: Updated. Exclude debug info for `Release' versions to reduce library size. * src/base/ftobjs.c (FT_Open_Face): Make it work as documented, this is, ignore `aface' completely if face_index < 0. Reported by David Osborn <spam@habitualhiatus.com>. * include/freetype/ftimage.h (FT_Outline_MoveToFunc, FT_Outline_LineTo_Func, FT_Outline_ConicToFunc, FT_Outline_CubicToFunc), src/smooth/ftgrays.c (gray_render_conic, gray_render_cubic, gray_move_to, gray_line_to, gray_conic_to, gray_cubic_to, gray_render_span, gray_sweep): Decorate parameters with `const' where appropriate.
