dnl PHP_GD_CHECK_FORMAT(format, [action-if-found])
dnl
dnl Build and run a program to determine if GD has support for the given
dnl format. The first argument is the proper-noun-capitalized name of the
dnl format -- basically the word Foo in gdImageCreateFromFoo -- such as
dnl Png. If support for format Foo exists, the second argument (the name
dnl of a constant) will be defined to 1. The reason for this charade is
dnl that gd defines "junk" versions of each gdImageCreateFromFoo function
dnl even when it does not support the Foo format. Those junk functions
dnl display a warning but eventually return normally, making a simple link
dnl or run test insufficient.
dnl Png. If support for "format" Foo exists, the "action-if-found" is executed.
dnl The reason for this charade is that gd defines no-op versions of each
dnl gdImageCreateFromFoo function even when it does not support the Foo format.
dnl Those no-op functions display a warning but eventually return normally,
dnl making a simple link or run test insufficient.
