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.
-bgimage | -no-bgimage
Whether to also draw the texture on the background.
-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 when blend is enabled.
-blend | -no-blend
Whether to enable blending. (see also offset_texture above)
-antialias | -no-antialias
Whether to anti-alias lines.
Number of verticies around the middle row of the blob (see also
Number of rows of verticies used to calculatethe blob, combined
with x_res to
indirectly determine the number of triangles used to draw
numbers give a smoother blob but increase calculation times
Number of points used to distort the blob.
Number of frames between changing images.
Speed at which fading occurs when changing images.
-fps | -no-fps
Whether to show a frames-per-second display at the bottom of
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.
