2019-09-17ui/egl: fix framebuffer readsGerd Hoffmann
Fix egl_fb_read() to use the (destination) surface size instead of the (source) framebuffer source for glReadPixels. Pass the DisplaySurface instead of the pixeldata pointer to egl_fb_read() to make this possible. With that in place framebuffer reads work fine even if the surface and framebuffer sizes don't match, so we can remove the guest-triggerable asserts in egl_scanout_flush().

2019-01-21egl-helpers.h: do not depend on X11 Window type, use EGLNativeWindowTypeAlexander Kanavin

2018-06-26Add gles support to egl-helpers, wire up in egl-headless and gtk.Gerd Hoffmann
Add support for OpenGL ES to egl-helpers. Wire up the new option for egl-headless and gtk UIs. egl-headless actually works fine. gtk hits a not-yet implemented code path in libEGL when trying to use gles mode: libEGL warning: FIXME: egl/x11 doesn't support front buffer rendering. (This is mesa 17.2.3).

2017-10-17egl-helpers: add egl_texture_blit and egl_texture_blendGerd Hoffmann
egl_texture_blit() blits a texture, simliar to egl_fb_blit() but by rendering the texture to the screen instead of using a framebuffer blit. egl_texture_blend() renders a texture with alpha blending, will be used to render the cursor to the screen.
