mirrorblob - Draws a wobbly blob that distorts the image behind it.

Draws a wobbling blob, making use of alpha blending, fog, textures, and
lighting, plus a ``frames per second'' meter so that you can tell how
fast your graphics card is... Requires OpenGL.
Specify which visual to use. Legal values are the name of a
visual class, or the id number (decimal or hex) of a specific
-window Draw on a newly-created window. This is the default.
-root Draw on the root window. -wire Render in wireframe instead of
Per-frame delay, in microseconds. Default: 10000 (0.01
-fog | -no-fog
Whether to enable fog.
-walls | -no-walls
Add walls for blob to hit.
-colour | -no-colour
Draw coloured blob. If also textured, the texture will have
color mixed in.
-texture | -no-texture
Whether to wrap a texture image on the blob.
-offset_texture | -no-offset_texture
Whether to ofset the texture calculations to only use a region
of the image
under the blob. This works well with a semi-transparent blob.
-blend | -no-blend
Whether to draw a transparent blob. (see also offset_texture
-antialias | -no-antialias
Whether to antialias lines.
Resolution of the tessellation used to calculate and draw the
numbers give a smoother blob but increase calculation times
Number of bumps used to distort the blob.
Time until loading a new image.
Time taken to transition between images.
Size multiplier for blob.
-fps Display the current frame rate, CPU load, and polygon count.
DISPLAY to get the default host and display number.
to get the name of a resource file that overrides the global
resources stored in the RESOURCE_MANAGER property.
