3b99fc4883 ColorButton: small rendering tweak/optimization for the alpha checkerboard. 
Inverting the pattern means that for our typical 3x3 grid we don't need to draw 1+4 rounded rectangles, only 1.
This also fix the slightly rounding mismatch when switching from a=255 to a<255 paths.

1d33ea939f DrawList: added ImDrawListFlags_NoTextPixelSnap to disable snapping of AddText() coordinates for a given scope. (#3437, #9417, #2291) 
This may evolve into a per-call ImDrawFlags option as well.
+ clip_rect.Max.y early out may be applied before truncation.

12b7977555 Tweak CalcTextSize() awkward width rounding/ceiling code to reduce floating-point imprecisions altering the result by 1 even at relatively small width. (#791) + apply same fudge factor to less important roundings. 
ceilf() is still measurable e.g. ballpark +0.5 for 200k calls.

6df50a0667 (Breaking) DrawList: swapped the last two arguments of AddRect(), AddPolyline(), PathStroke(). thickness<>flags. 
Added inline redirection functions when IMGUI_DISABLE_OBSOLETE_FUNCTIONS is off.
Marked the old functions are =delete when IMGUI_DISABLE_OBSOLETE_FUNCTIONS is on, to allow for better type-checking.
The aim is to be able to use/add flags to more ImDrawList functions, and making existing functions consistents was deemed very desirable.

f83a378d62 TabBar: changed edge's TabItem ClipRect to not pass an inverted PushClipRect(). 
While not currently a problem, it would be if ImRect::Overlaps() is changed to use <= instead of < (cc: #3976 which deal with Contains but sort of similar topic).
Changing ImDrawList::PushClipRect()'s intersect_with_current_clip_rect path to use ClipRectFull() would also fix this, but it may ambiguous there which behavior would be correct.

fbe973a8d0 Cast this to (void*) in zero-clearing memset calls to fix -Wnontrivial-memcall (#9247, #8295, #8129, #8135) 
Clang 20+ warns on memset(this, ...) for non-trivially copyable types via -Wnontrivial-memcall.
Should separately investigate -Wnonontrivial-memaccess vs -Wnonontrivial-memcall.
