There is a new command,
\suppressfloats, and a new `float
specifier'. These will enable people to gain better
control of LaTeX's float placement algorithm.
This command stops any further floating environments from being placed
on the current page. With an optional argument, which should be either
b (not both), this restriction applies only to putting
further floats at the top or at the bottom. Any floats which would
normally be placed on this page are placed on the next page instead.
The extra float location specifier: !
This can be used, along with at least one of h, t, b and p, in the location optional argument of a float.
If a ! is present then, just for this particular float, whenever it is processed by the float mechanism the following are ignored:
Note that its presence has no effect on the production of float pages.
A ! specifier overrides the effect of any
command for this particular float.
