If I recall,
someone posted that ATI rage 128 used on the Macs posted a value
of GL_DEPTH_BITS = 24 when ldglite is run.  Can someone verify
this?

GL_VERSION = 1.1 ATI-1.1
GL_EXTENSIONS = GL_APPLE_specular_vector GL_APPLE_transform_hint
GL_APPLE_packed_pixel GL_APPLE_client_storage GL_APPLE_client_address_range
GL_ARB_transpose_matrix GL_EXT_clip_volume_hint GL_EXT_rescale_normal
GL_NV_texgen_reflection GL_IBM_rasterpos_clip GL_ARB_multitexture
GL_ARB_texture_env_add GL_ARB_texture_env_combine GL_EXT_abgr GL_EXT_bgra
GL_EXT_texture_env_add GL_EXT_texture_lod_bias GL_EXT_compiled_vertex_array
GL_SGIS_texture_edge_clamp
GL_VENDOR ='ATI Technologies Inc.'
GL_RENDERER ='Rage 128 OpenGL Engine'
GL_RGBA_BITS: (5, 5, 5, 1)
GL_DEPTH_BITS = 24
GL_STENCIL_BITS = 8
Buffer Swap Mode = 0

So, the answer is yes.

Also, could someone try some perspective mode viewing with these
command line settings to see if it fixes the bleeding?

-z100 -Z2000 -J

I don't know what you are talking about, but I ran it with those settings
and it generated this:

(...) Hmmm, not much bleeding there. What do you get when you run with just the -J switch? Is it more like this? (URL) of nasty edge line bleeding there! Don (22 years ago, 6-Jun-02, to lugnet.cad.dev.mac)

While following up on the latest round of bug reports I noticed this page. (URL) pics, but while viewing them I realized that all of the perspective (non-orthographic) views displayed a lot of z-fighting (underlying surfaces and lines bleeding (...) (22 years ago, 6-Jun-02, to lugnet.cad.dev.mac)
