TIGR 2.0

Additions

• The Post-FX pixel shader is now customisable
• Cursor can be hidden for custom software cursor drawing
• PNG loading now supports 1, 2, 4 and 8 - bit palette formats in addition to 8-bit color component formats

Fixes

• PNG loading
  • First row was previously filtered incorrectly, which made font loading hard
  • Transparency handling is corrected to use transparency palette instead of palette index 0
• X11 input handling now uses polling instead of event processing, for a slight latency improvement
