Breaking Changes

• Renamed drawing.h to immediate2d.h.

• The header and implementation have been merged into a single .h file (in the stb-style). Instead of compiling immediate2d.cpp separately, now, in exactly one of your own cpp files, add this line before the immediate2d.h include: #define IMM2D_IMPLEMENTATION.

• Instead of changing the Width/Height/Scale in the header itself, you can now use #define IMM2D_WIDTH 640, #define IMM2D_WIDTH 480, and #define IMM2D_SCALE 2 just above your IMM2D_IMPLEMENTATION define in your own code. Now you shouldn't ever need to modify the immediate2d.h header itself.

• Renamed the top-level user function called by the library to run() instead of main() (which could cause some name collisions depending on your environment).

• Renamed SetPixel to DrawPixel to be more consistent with the rest of the drawing APIs.

• All the bool filled parameters on shape drawing got split out into separate fill/stroke colors, which can save a call in the best case and is more readable in the worst case.

• Split UseAntiAliasing(bool) into the separate, parameterless UseAntiAliasing() and StopAntiAliasing(), which should be a little more legible to beginners.

New Stuff

• Added LoadImage, DrawImage, ImageWidth, and ImageHeight calls to work with images! Many file types are supported along with reading from disk, resources embedded in the .exe, or directly from a Base64-encoded string. Check the new examples to see how to use them.

• There were many "secret" functions (if you read the implementation) that have now been exposed and documented in the header: MakeColorHSB, DrawArc, DrawString, LastBufferedKey, ClearInputBuffer, PlayMusic, and ResetMusic.

• Added buildAll.bat (and cleanAll.bat) which can build (and delete) the examples from a Visual Studio "Native Tools Command Prompt". If you're interested in building your own project from the command line, these scripts might be a good place to start.

• The quick reference PDF has been updated to include HSB colors and image loading/drawing.

Fixes / Neutral Changes

• The internal GDI+ based line drawing now uses round end caps, which should join end-to-end better with larger thicknesses.

• Double-buffered Present could sometimes cause the screen to flicker.
