public header (raylib.h) with <windows.h>

[osom8979]

I have been working on mixing raylib with imgui in my project.

It was a problem with duplicated symbols on the Windows platform, but this was solved by fixing the code. (ex. Rectangle, DrawText, etc ...)

As a result, we have succeeded but we need to constantly respond to the upgrade.

Do you have plan to modify the public header (raylib.h) to coexist with the <windows.h> file?

Hi @osom8979, where is windows.h included? That collision shouldn't happen. Most probably windows.h colliding functions are not being used anywhere, actually, colliding symbols probably come from libraries neither required by the program...

I've been dealing with those windows.h collisions for some years and there is always some wayto avoid them. For example, here it is a possible solution to just include what it's really needed from windows.h:

/* 
  @raysan5: To avoid conflicting windows.h symbols with raylib, some flags are defined
  WARNING: Those flags avoid inclusion of some Win32 headers that could be required 
  by user at some point and won't be included...
*/

There are also some libraries out there that divide windows.h into separate pieces.

No plans to modify raylib functions for the moment.
