2016-01-27Update minuitwrp graphics in line with latest minuiEthan Yonker1-45/+46
Note: events.cpp is still old code renamed to cpp to make it easier to call functions like gr_fb_width(). I had to modify AOSP fbdev code to provide a separate memory surface for drawing to as drawing directly to the framebuffer resulted in rendering taking about 5 times longer. I also modified AOSP adf code to provide a separate memory surface for drawing for the same performance reasons. The Nexus 9 supports adf graphics. Overlay graphics work on at least one device. Overlay provides a separate memory buffer already so performance is good. I do not have a drm device yet that I know of. I made some attempt to update the drm code to determine the correct pixel format based on the drm graphics format, but what is available in pixel flinger and what is available in drm do not line up all that well. Reports are that the Pixel C is using drm graphics, but performance is slow, likely due to the use of a mmap instead of a memory buffyer. Change-Id: Ibd45bccca6ac2cb826037aa9b2aa5065cf683eed

2014-10-14Add support for TrueType fontsVojtech Bocek1-0/+731
* Keeps original font system in place * Uses the same API as original font system: - You can render only one line at a time - You can only use one font and color for one gr_text* call * Caches all rendered text, with a string cache limited to 400 entries, then it trucates to 250, which results in memory usage hovering around 5-10MB Change-Id: I36107b9dcd8d57bae4486fce8b8f64e49ef3d906 Signed-off-by: Vojtech Bocek <vbocek@gmail.com>
