Avoid naming collision with imgui_demo.cpp's HelpMarker() for unity builds.

Push a clipping rectangle for both ImGui logic (hit-testing etc.) and low-level ImDrawList rendering. - When using this function it is sane to ensure

It is the map we need iterate to find valid items, since we don't have "alive" storage anywhere

Computes the bitwise AND-NOT of the four single-precision, floating-point values of a and b. r0 := ~a0 & b0 r1 := ~a1 & b1 r2 := ~a2 & b2 r3 := ~a3 &

Blend packed single-precision (32-bit) floating-point elements from a and b using mask, and store the results in dst. https://www.intel.com/content/ww

FIXME: _mm_getcsr() implementation supports reading the rounding mode only.

Compare packed unsigned 32-bit integers in a and b, and store packed maximum values in dst. https://www.intel.com/content/www/us/en/docs/intrinsics-gu

Compare packed unsigned 32-bit integers in a and b, and store packed minimum values in dst. https://www.intel.com/content/www/us/en/docs/intrinsics-gu

Computes the bitwise OR of the 128-bit value in a and the 128-bit value in b. r := a | b https://msdn.microsoft.com/en-us/library/vstudio/ew8ty0db(v

Sets the 8 signed 16-bit integer values to w. r0 := w r1 := w ... r7 := w https://msdn.microsoft.com/en-us/library/k0ya3x0e(v=vs.90).aspx

Computes the approximations of square roots of the four single-precision, floating-point values of a. First computes reciprocal square roots and then

Interleaves the lower 8 signed or unsigned 8-bit integers in a with the lower 8 signed or unsigned 8-bit integers in b. r0 := a0 r1 := b0 r2 := a1 r3
