* adds DrawTexturedPoly with example

* the actual example ... ahem

* moved DrawTexturePoly to textures function and example
NB function name changed to fit with other DrawTextureXXX functions
(no "d" )

Co-authored-by: codifies <you@example.com>

This function was renamed for consistency in raylib 3.0, just unified all examples to use TextFormat() instead of FormatText()

Probably more useful...

Examples have been renamed for coherence with raylib modules and test
examples have been merged into examples folder.
