Please feel free to > try it out, there are huge speed increases for font and image display, > and also a demo of 32bpp compositing, which runs on any > truecolor display (compositedemo.sh, blitdemo.sh).

Subdrivers for 1/2/4/8/15/16/24/32bpp have no > control > branches in inner loops for highest speed. For systems without > framebuffers, like desktop X11 for testing, all image data is computed > using framebuffer subdrivers, and then blitted once to final display > using an automatic graphics Update() operation. For systems with > framebuffers, drawing is done directly to screen for speed, with support > for > future "buffered" windows for late-stage final compositing. > o All conversion blits support all portrait modes, stretching, raster ops, > and srcover alpha blending. > o GdArea, GdReadArea, GdBitmap and all fonts use fast conversion blits. > o New conversion blits can be added for speed for specific systems, and > slower draw code is still available for 1/2/4/8bpp palette systems. > o Most image loaders (png, jpg, etc) read into internal RGBA format for > easy use in compositing and alpha blending. > o Runtime auto-portrait mode switching now possible without application > image recomputation requirements.
