# TinyGL- New and Improved
+A rework of Fabrice Bellard's TinyGL (still compiling with -std=c99) to be

It is a small, suckless Software-only partial GL 1.1 implementation.
The original project was by Fabrice Bellard. We have forked it.

The changelog is as such:
+
* Disabled all non-RGBA rendering modes. The only supported mode is now RGBA.
* Implemented new functions and some of GL 1.1's prototypes including polygon stipple.
-* Fixed a myriad of bugs
-NEW FUNCTIONS

+* Fixed a myriad of bugs and... weirdnesses

+Note that this Softrast **is not GL 1.1 compliant** and does not constitute a complete GL implementation.
+
+You *will* have to tweak your code to work with this library. That said, once you have, it will run anywhere that you can get
+C99. TinyGL has very few external dependencies.
+
+
+
+Notable limitations:
+
+* The only supported texture size and format is RGB 256x256
+
+* there is no GL_BLEND compatibility whatsoever
+
+* A lot of prototypes are missing.
+

+
+
+### NEW FUNCTIONS
+
+These are functions not in the GL 1.1 spec that i've added to make this library more useful.

### glDeleteList
An easier to use version of glDeleteLists. glDeleteLists is also implemented.

## FULLY COMPATIBLE WITH RGBA!
The library is now configured properly for RGBA rendering. Note that the output *is actually ABGR*
but adjusting it is easy, see the SDL examples under SDL_EXAMPLES (They require SDL 1.2 and Mixer to compile)
+
+It is a notable loss in this version of TinyGL that 16 bit color support was removed. The only supported mode is 32 bit
+
+This was done to keep this library maintainable.
