=head1 NAME
SDLx::FPS - a more convenient way to set a framerate
=head1 SYNOPSIS
use SDLx::FPS;
my $fps = SDLx::FPS->new(fps => 60);
while(1) { # Main game loop
# Do game related stuff
$fps->delay;
}
=head1 DESCRIPTION
SDLx::FPS simplifies the task of giving your game a framerate.
Basically, it combines the methods of C<SDL::GFX::Framerate> and C<SDL::GFX::FPSManager> into a single module.
Use it to delay the main loop to keep it at a specified framerate.
=head1 METHODS
=head2 new
my $fps = SDLx::FPS->new( fps => 30 );
No arguments are required, if no C<fps> is specified, the default FPS is 30.
=head2 set
$fps->set($new_framerate);
Same as C<SDL::GFX::Framerate::set>.
Set the new desired framerate.
=head2 get
Same as C<SDL::GFX::Framerate::get>.
Get the currently set framerate.
=head2 delay
Same as C<SDL::GFX::Framerate::delay>.
Generate a delay to accommodate currently set framerate.
Call once in the graphics/rendering loop.
If the computer cannot keep up with the rate (i.e. drawing too slow), the delay is 0 and the delay interpolation is reset.
=head2 framecount
Return the C<framecount>.
=head2 rateticks
Return the C<rateticks>.
=head2 lastticks
Return the C<lastticks>.
=head2 rate
Return the C<rate>.
