Bodmer 9666314eb6 Support for ESP32 PSRAM added 
If PSRAM is fitted and enabled the Sprites are now created in PSRAM.
This makes multiple full screen buffers possible!

Bodmer 1a0b37097a Add new anti-aliased (smooth) font examples + bug fixes 
Four new examples have been added to show different methods of rendering
the anta-aliased fonts.  A few minor bugs have been corrected associated
with the font rendering. drawNumber and drawFloat handle fixed width
mono fonts with no digit movement.

Update Sprite.cpp 
Hi,
I found a bug.

_width and _height need to be initialized properly.

That is because they are used in drawString(). Lines 4118 and 4120 in TFT_eSPI.cpp.
