OpenGL ES

• Embed purpose OpenGL API.
• Mostly in iOS, Android, Browser GL API
• Removal of glBegin/glEnd was good a decision.
• From 2.0 fixed function pipeline is removed and only shaders are used for effects.
• OpenGL ES 1.1
• OpenGL ES 2.0
• OpenGL ES 3.0
• GLSL ES

Pixman

• PIXel MANipulation library
• Software rendering backend.
• repository
• pixman.h
• Writing png from pixman_image_t
  • before saving to PNG it renders to PIXMAN_a8r8g8b8 image
• Fixing SIZE_MAX error
  • SIZE_MAX is not in standard(?)
• pixman_image_create_bits
  • clears bits when NULL pointer is passed
  • to skip clearing use _no_clear function
• operators
