_WinAPI_FloatToInt() --> obsolete in GDIPlus.au3

[Zedna]

_WinAPI_FloatToInt() is declared in WinApi.au3 UDF
and it's used in GDIPlus.au3 UDF only.

PaulIA created it in his Auto3Library as workaround for missing float type support in DllCall().

But later Jon added support for float type into DllCall()
but PaulIA has left forum already so this (now not neccessary) workaround is still there.

Princip of workaround was in creating structure for DllCall with int type instead of float and place data into it converted by _WinAPI_FloatToInt(). Then in DllCall() was used type int instead of float.

It's nice visible in this example for _GDIPlus_DrawImagePoints()
I removed workaround and tested it on WINXP - it works OK:

_GDIPlus_DrawImagePoints2() is corrected original _GDIPlus_DrawImagePoints():
