Fixes#17030 , or at least improves on it - for optimal performance that
big framebuffer used for bloom should be split like in Killzone, but it's not trivial.
The regression in 1.14 is fixed with this, at least.
I tried it with a few other games with no issues - it seems games are
using TexFlush when needed. But let's see if it really is safe to rely
on that...
There might also be other places we should call DiscardFramebufferCopy
in.
And thus change of depth buffer scale/offset.
Previously, old depth buffers with values that now are out of range
could stick around, causing #16941. This clears them to the expected 0
value, which helps Outrun. Ideally we should convert depth buffers to
the new format, but if we can get away without that, that's also nice.
This is enough for #16941.
Requested an init command buffer outside the frame, which is dangerous
and caused validation problems with command pool resets.
Would like to assert on insideFrame in GetInitCmd, but we use it from
some init code where it does work correctly. Might clean that up at some
point.
