Specifies the name of a resource file to be included in an application or
library. The named file must be valid resource file (Windows 32-bit or OS/2
format) and the default extension for filenames is .RES.
Syntax:
{$R filename.RES}
Remarks:
When a {$R filename} directive is used in a unit, the specified file name
is simply recorded in the resulting unit file. No checks are made at that
point to ensure that the filename is correct and that it specifies an
existing file.
Win32 target:
Old 16-bit Windows resource format is not allowed.
