I'm currently running up against the limitations of the lcd_draw functions I want these functions to be able to be used on any size buffer not just buffers with a stride matching the underlying device [DONE] allow the framebuffer to be decoupled from the device framebuffer [DONE need examples] allow for some simple blit like transformations [DONE] remove the device framebuffer from the plugin api [DONE}ditto remote framebuffer [DONE] remove _viewport_get_framebuffer you can call struct *vp = lcd_set_viewport(NULL) and vp->buffer->fb_ptr while remote lcds may compile (and work in the sim) its not been tested on targets [FIXED] backdrops need work to be screen agnostic [FIXED] screen statusbar is not being combined into the main viewport correctly yet [FIXED] screen elements are displayed incorrectly after switch to void* [FIXED] core didn't restore proper viewport on splash etc. [NEEDS TESTING] remote lcd garbled data [FIXED] osd lib garbled screen on bmp_part [FIXED] grey_set_vp needs to return old viewport like lcd_set_viewport [FIXED] Viewport update now handles viewports with differing buffers/strides by copying to the main buffer [FIXED] splash on top of WPS leaves old framebuffer data (doesn't redraw) [UPDATE] refined this a bit more to have clear_viewport set the clean bit and have skin_render do its own screen clear scrolling viewports no longer trigger wps refresh also fixed a bug where guisyncyesno was displaying and then disappearing [ADDED!] New LCD macros that allow you to create properly size frame buffers in you desired size without wasting bytes (LCD_ and LCD_REMOTE_) LCD_STRIDE(w, h) same as STRIDE_MAIN LCD_FBSTRIDE(w, h) returns target specific stride for a buffer W x H LCD_NBELEMS(w, h) returns the number of fb_data sized elemenst needed for a buffer W x H LCD_NATIVE_STRIDE(s) conversion between rockbox native vertical and lcd native stride (2bitH) test_viewports.c has an example of usage [FIXED!!] 2bit targets don't respect non-native strides [FIXED] Few define snags Change-Id: I0d04c3834e464eca84a5a715743a297a0cefd0af
