-------------------------------------------
-
-OUTSTANDING BUGS
-
-demos/reflect - reading back Z on Voodoo3, image offset to right
-	Fixed in latest Glide.
-
-Q3 - some polygons drawn as vertical strips, similar to bug that was
-	seen in demos/fire.  Voodoo3 only.  May be related to glDepthMask
-	or glColorMask.
-
-book/fog - not fogging
-	Fog in orthograph mode still not implemented.  Checking with
-	3dfx engineers for ideas.
-
-Q3 demo crashes after changing display settings
-	but the full Q3 game version seems OK.
-
-
-
-MORE OUTSTANDING BUGS
-
-private context was NULL! causing immediate failure of any glx prog. cant
-reproduce after restarting the X server. putting it down as halluc.
-
-texture object image was NULL, causing segmentation failure. happens with
-prboom. ive put a check in tdfx_texstate.c but this isn't a fix.
-
-prboom, wall textures near first chainsaw aren't bound properly. sideways
-movements causes the wall textures to move with you. prboom busted?
-
-16bpp mode, quake3, windowed, q3dm1, floor under rocketlauncher bands. it
-looks like multitexturing gone wrong. i'll disable a tmu and test.
-
-sof, polygons appear at wrong x,y,z positions, intermittent, have not yet
-found reliable way of reproducing. culling? sometimes polys disappear.
-
-descent3 is all black in 16bpp mode - FIXED (palette problems)
-
-smeared pixels in quake3 - FIXED (texture memory overlapped FB)
-
-

- * Because the Linear Frame Buffer is not necessarily aligned
- * with the depth buffer, we have to do some fiddling
- * around to get the right addresses.
- *
- * Perhaps a picture is in order.  The Linear Frame Buffer
- * looks like this:
- *
- *   |<----------------------info.strideInBytes------------->|
- *   |<-----physicalStrideInBytes------->|
- *   +-----------------------------------+xxxxxxxxxxxxxxxxxxx+
- *   |                                   |                   |
- *   |          Legal Memory             |  Forbidden Zone   |
- *   |                                   |                   |
- *   +-----------------------------------+xxxxxxxxxxxxxxxxxxx+
- *
- * You can only reliably read and write legal locations.  Reads
- * and writes from the Forbidden Zone will return undefined values,
- * and may cause segmentation faults.
- *
- * Now, the depth buffer may not end up in a location such each
- * scan line is an LFB line.  For example, the depth buffer may
- * look like this:
- *
- *    wrapped               ordinary.
- *   +-----------------------------------+xxxxxxxxxxxxxxxxxxx+
- *   |0000000000000000000000             |                   | back
- *   |1111111111111111111111             |                   | buffer

- * where each number is the scan line number.  We know it will
- * be aligned on 128 byte boundaries, at least.  Aligning this
- * on a scanline boundary causes the back and depth buffers to
- * thrash in the SST1 cache.  (Note that the back buffer is always
- * allocated at the beginning of LFB memory, and so it is always
- * properly aligned with the LFB stride.)
- *
- * We call the beginning of the line (which is the rightmost
- * part of the depth line in the picture above) the *ordinary* part
- * of the scanline, and the end of the line (which is the
- * leftmost part, one line below) the *wrapped* part of the scanline.
- * a.) We need to know what x value to subtract from the screen
- *     x coordinate to index into the wrapped part.
- * b.) We also need to figure out if we need to read from the ordinary
- *     part scan line, or from the wrapped part of the scan line.
- *
- * [ad a]
- * The first wrapped x coordinate is that coordinate such that
- *           depthBufferOffset&(info.strideInBytes) + x*elmentSize  {*}
- *                            > physicalStrideInBytes
- *     where depthBufferOffset is the LFB distance in bytes
- *     from the back buffer to the depth buffer.  The expression
- *           depthBufferOffset&(info.strideInBytes)
- *     is then the offset (in bytes) from the beginining of (any)
- *     depth buffer line to first element in the line.
- * Simplifying inequation {*} above we see that x is the smallest
- * value such that
- *         x*elementSize > physicalStrideInBytes                      {**}
- *                            - depthBufferOffset&(info.strideInBytes)
- * Now, we know that both the summands on the right are multiples of
- * 128, and elementSize <= 4, so if equality holds in {**}, x would
- * be a multiple of 32.  Thus we can set x to
- *         xwrapped = (physicalStrideInBytes
- *                      - depthBufferOffset&(info.strideInBytes))/elementSize
- *                      + 1
- *
- * [ad b]
