Vulkan backend: g_FrameIndex not used fix -> huge perf gain ...

Added a macro to switch between unlimited frame rate (VK_PRESENT_MODE_IMMEDIATE_KHR) and limited to 60 fps (VK_PRESENT_MODE_FIFO_KHR). Only the latter mode is guaranteed to be available, but the former one most likely is.

Combo, ListBox: Extra const correctness.

Minor documentation tweaks

Examples: DirectX9: Explicitely setting viewport to match that other examples are doing (#937)

Demo: comments

const correctness for Combo and ListBox ...

Since Combo and ListBox only read and display the list of items, they
should not modify the pointers inside the array of pointers passed in.
Adding "const" here makes it possible to call these functions with such
an array of const pointers. Previously, a cast to "const char**" was
required as a workaround, otherwise there was a compile error.
