Specifying a threshold size is a bit more flexible, and allows the option of converting even 1-pixel points to triangles (set threshold=0). Also, remove 0.25 pixel bias in wide_point(). |

CROSS-PLATFORM PORTABILITY GUIDELINES FOR GALLIUM3D = General Considerations = The state tracker and winsys driver support a rather limited number of platforms. However, the pipe drivers are meant to run in a wide number of platforms. Hence the pipe drivers, the auxiliary modules, and all public headers in general, should stricly follow these guidelines to ensure = Compiler Support = * Include the p_compiler.h. * Don't use the 'inline' keyword, use the INLINE macro in p_compiler.h instead. * Cast explicitly when converting to integer types of smaller sizes. * Cast explicitly when converting between float, double and integral types. * Don't use named struct initializers. * Don't use variable number of macro arguments. Use static inline functions instead. = Standard Library = * Avoid including standard library headers. Most standard library functions are not available in Windows Kernel Mode. Use the appropriate p_*.h include. == Memory Allocation == * Use MALLOC, CALLOC, FREE instead of the malloc, calloc, free functions. * Use align_pointer() function defined in p_util.h for aligning pointers in a portable way. == Debugging == TODO
