another patch that may aid in understanding what's going on
Just to follow up again, we played around a bit more and figured some stuff out
but we're still kind of banging around in the dark.
What we learned:
- The reason vector_justify = TRUE fixed one of the tests, but kept some
failing is because it was reversing X and Y coordinates, so only the first 3
component sshort test run was getting placed properly (because the test case
has x and y start with the same value). The subsequent ones were growing down
instead of right.
- of course we can then get it working by changing the swizzle order in
u_format.csv to yxz1 for the 3 component short and 3 component half float
tests. clearly not the "right" fix, but was interesting to see all the tests
working.
- if i leave vector_justify to FALSE, but change attachment 130980 to use
fetch_width instead of format_desc->block.bits then all the 3 component sshort
tests and half float tests start working, but then r32g32b32_sscaled start
failing. So, the above patch fudges it to make everything in draw-vertices and
draw-vertices-half-float work. Obviously not shippable, but might aid in
figuring out what's going on?
