6371cd7b1d DrawList: added stroke position to path rendering.
- added generic stroke position to all path rendering
- removed stroke folding in favor of limiting the miter width (simplifies the geometry cases)
- removed fractional stroke rendering in favor of using the integer sized rendering for everything
  - the rationale is that the in-between sizes are a bit blurry anyways, and the error we get from scaling is visually acceptable
- added stroke position option for the demo
- updated the degenerate shape handling
- remove AddLine() stroke pos handling
- removed up commented out code.

b097a7bd33 DrawList: added better handling for rendering degenerate geometry. (2183, 7972)
- Add ImDrawFlags_MiterOnly which is used to indicate that a path contains simple geometry and can be rendered using mitered corners
- Added handling of degenerated shapes for stroked rectangle, circle, ngon, and ellipse
- Render shapes filled when outline covers the whole shape
- Clamp very small circles and ngons, and use alpha fade below one pixel
- Added correct offset for ellipse

ce44b4e8be DrawList: added improved polyline rendering. (2183, 7972)
- added 2 variants of polyline rendering
- one handles integersized thickness using one strip of triangles along the line
- second handles any thickness using 2 strips of triangles long the line

- fixed lineV() centered offset
- renamed ImDrawFlags_StrokeCenterPixelAligned to ImDrawFlags_StrokeCenterAligned.
- reduced debug build indirections.

927df56807 DrawList: Textured Round Corners: Added flags to disable textured rounded corners (1962)
- added ImFontAtlasFlags_NoBakedRoundCorners which controls if rounded corners should be baked to texture
- added ImDrawListFlags_RoundCornersUseTex which controls if we should try to use textured roudned corners
- fixed how _FringeScaleIsInteger is calculated (we want to detect integer pixel scale)
- fixed how _FringeScale is used with textured rounded corners

456858d50f DrawList: Textured Round Corners: implemented faster render path for stroked rectangles. (1962)
- added check to render simpler geometry when (stroked) rectangle has integer coords
- render non.rounded with 4 non-AA rectangles
- added textures for corners of 1-3 thickness and 1-16 rounding
- use textured corners when possible, or fallback to generic one

76184b6308 (Breaking) DrawList: removed half pixel offset from ImDrawList::AddLine()
- removed half pixel offset from ImDrawList::AddLine()
- added ImDrawList::AddHorizontalLine() and ImDrawList::AddVerticalLine() which draw line to the side of the specified line
- Change uses of AddLine() which were obviously vertical and horizontal  to use the v and h lines
- Fixed layouting issues from above changes
- Changed primitives demo to use vline and hline
- Fixed angled header to match original
- Fixed separator line to match original
- Fixed caret to match original
- Fix separator vertical alignment
- Added stroke pos, which controls how stroke is draw relative to the shape
- Kept legacy mode which does 1/2px inset
- Added stroke pos support for Rect, Circle, Ngon, and Ellipse
- add stroke pos to hline and vline
- Added drawflag ImDrawFlags_TruncateCoords which allows to hint the renderer that the input is snapped to pixels (can disable AA in some cases)
- Implemented 9-slice renderer for rounded corners
- Remove ImDrawFlags_TruncateCoords flag in favor of detecting truncated coords.
- Renamed to AddLineH(), AddLineV()
- Removed ImDrawStrokePos, folded into ImDrawFlags

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.
