Adds a style variable to Selectable that allows clients to specify the
text alignment within Selectables, adds a section in the demo to
demonstrate selectable text alignment, and a pair of sliders in the
style editor to change selectable alignment on the fly.
In terms of implementation, this one is extremely simple: Selectable was
already calling an API that supports text alignment, but had hard-coded
it to top-left. This changes that to just pass the style variable
straight through to RenderTextClipped. Backwards-compatibility is
preserved by defaulting the text_align parameter to (0, 0), i.e.,
top-left.
This also fixes a bug with selectable text rendering that caused
right-aligned text in a selectable to be clipped incorrectly, because
the wrong clipping rectangle was being used.
AntiAliasedLines=true;// Enable anti-aliasing on lines/borders. Disable if you are really short on CPU/GPU.
AntiAliasedFill=true;// Enable anti-aliasing on filled shapes (rounded rectangles, circles, etc.)
CurveTessellationTol=1.25f;// Tessellation tolerance when using PathBezierCurveTo() without a specific number of segments. Decrease for highly tessellated curves (higher quality, more polygons), increase to reduce quality.
SelectableTextAlign=ImVec2(0,0);// Alignment of selectable text when button is larger than text.
boolAntiAliasedLines;// Enable anti-aliasing on lines/borders. Disable if you are really tight on CPU/GPU.
boolAntiAliasedFill;// Enable anti-aliasing on filled shapes (rounded rectangles, circles, etc.)
floatCurveTessellationTol;// Tessellation tolerance when using PathBezierCurveTo() without a specific number of segments. Decrease for highly tessellated curves (higher quality, more polygons), increase to reduce quality.
ImVec2SelectableTextAlign;// Alignment of selectable text when selectable is larger than text. Defaults to (0,0) for top-left alignment.
