Just for clarification, no plans to remove libc dependency, just did some code analysis to see how much raylib depend on stardard C library. My conclusions:
- stdlib.h: primary dependency is for malloc() and free()
- stdio.h: primary dependency is for FILE access, maybe it could go through a custom ABI?
- string.h: just around 8 functions required
- math.h: just around 8 functions required
- others: 1-2 functions required for some other headers
* We get the video mode from the target monitor and use that to set, therefore
keeping windowed-fullscreen
* Added a GLFW_AUTO_ICONIFY 0 hint so that glfw does not minimize the window
when changing focus from a windowed fullscreen window. This is more expected
behavior for windowed full screen, when a user alt-tabs or clicks on a window in
the other monitor, they expect their windowed-fullscreen window to remaining up.
If press/release events for a mouse button come too fast, then using
`IsMouseButtonReleased()` does not work. This has been noticed when
using a touchpad on Linux when tapping with two fingers two emulate
right mouse button click.
The situation looks like this:
```
BeginDrawing <-- current==released, previous==released
Pressed <-- current=pressed
Released <-- current=released
IsMouseButtonReleased <-- returns false because current==previous
EndDrawing <-- previous=released
```
The fix is to update the previous mouse button state in addition to
current mouse button state when `MouseButtonCallback()` is called by
glfw. Now the situation is as follows:
```
BeginDrawing <-- current==released, previous==released
Pressed <-- current=pressed, previous=released
Released <-- current=released, previous=pressed
IsMouseButtonReleased <-- returns true because current!=previous
EndDrawing <-- previous=released
```
