gzdoom/src/r_plane.h
Randy Heit c412b42703 - Fixed: cycle_t was still a DWORD and not a QWORD under GCC.
- The stat meters now return an FString instead of sprintfing into a fixed
  output buffer.
- NOASM is now automatically defined when compiling for a non-x86 target.
- Some changes have been made to the integral types in doomtype.h:
  - For consistancy with the other integral types, byte is no longer a
    synonym for BYTE.
  - Most uses of BOOL have been change to the standard C++ bool type. Those
    that weren't were changed to INTBOOL to indicate they may contain values
    other than 0 or 1 but are still used as a boolean.
  - Compiler-provided types with explicit bit sizes are now used. In
    particular, DWORD is no longer a long so it will work with both 64-bit
    Windows and Linux.
  - Since some files need to include Windows headers, uint32 is a synonym
    for the non-Windows version of DWORD.
- Removed d_textur.h. The pic_t struct it defined was used nowhere, and that
  was all it contained.
