We need to figure out if the compression format changes.
without this texcmp segfaults if you change format
enough times.

Converted r100 to use shared debug code with sed and fast compile check. New
code has compability layer so old debugging code doesn't have to be changed
all immidiatly.

|
This stuff was a vestige of the r600 bring up and
now mostly serves to periodically break the build.

another case of image never matching miptree in case of compressed textures
|
|
- fix not respecting required hardware stride with compressedTexImage -
this fixes #22615.
- make sure correct stride is used in various places
- fix stored miptree never matching with a TexImage call with compressed
texture
- don't always store data with compressedtexsubimage at offset 0,
and actually use the supplied pixel data... (untested)
- make sure rows for compressed texture handling are rounded up not down
Note that trying to access stored compressed textures in hardware miptrees
from core mesa (get_compressed_teximage, swrast fallbacks) can't work correctly,
since RowStride isn't really set to anything useful, plus some places (at least
get_compressed_teximage) assume this data has native stride and no padding.

fixes texwrap

use the actual value set in the context
|

This doesn't make things worse but according to sroland it
is how the GPU hw expects things on the r100/r200
|
|
Looks like r400 based IGP chips require 64 byte alignment
|
|
Some debugging code got there by accident
|
|
- remove unused fields
- remove unused defines and macros
- flatten one structure

The mip tree creation would crash if the first baselevel image to be uploaded
was not the positive-x image.
Found with Sauerbraten, also added a regression test to Piglit.

tested on r200, texcmp works. May need more verification

This fixes a few regression in piglit, and adds some debug to the mipmap code
