+## The future... ##
+
+**1. Performance improvements**
+I have made some changes that will be uploaded soon that improves sprite and image rendering performance by up to 3x faster on the ESP8266. These updates are currently being tested/debugged.
+
+**2. Anti-aliased fonts**
+
+I have been experimenting with anti-aliased font files in "vlw" format generated by the free [Processing IDE](https://processing.org/). This IDE can be used to generate font files from you computers font set and include **any** Unicode characters. This means Greek, Japanese and any other UTF-16 glyphs can be used.
+
+It would be possible to compress the vlw font files but the rendering performance to a TFT is still good when storing the font file(s) in SPIFFS.
+
+Here are some screen grabs (from an ILI9341 240x320 pixel TFT) showing 32pt characters.  Can you spot the difference between anti-aliased and 2 colour "bitmap" fonts?

+
+Here is another screenshot, showing the anti-aliased Hiragana character Unicode block (0x3041 to 0x309F) in 24pt from the Microsoft Yahei font:

+Currently these are generated from a sketch, but when I have the Alpha blending sorted for colour backgrounds the plan is to build the rendering code into the TFT_eSPI library.  Watch this space " " for updates!
