-/* Minimal swrast-based dri loadable driver.
- *
- * Todo:
- * -- Use malloced (rather than framebuffer) memory for backbuffer
- * -- 32bpp is hardwared -- fix
- *
- * NOTES:
- * -- No mechanism for cliprects or resize notification --
- * assumes this is a fullscreen device.
- * -- No locking -- assumes this is the only driver accessing this
- * device.
- * -- Doesn't (yet) make use of any acceleration or other interfaces
- * provided by fb. Would be entirely happy working against any
- * fullscreen interface.
- * -- HOWEVER: only a small number of pixelformats are supported, and
- * the mechanism for choosing between them makes some assumptions
- * that may not be valid everywhere.
