[Mesa-dev] [PATCH 1/2] egl: fix type mismatch error type in _eglInitSurface

[Tapani Pälli]

EGL spec defines EGL_BAD_MATCH for windows, pixmaps and pbuffers in
case where user creates a surface but config does not support rendering
to such surface type.

Following quotes are from EGL 1.5 spec 3.5 "Rendering Surfaces" :

for eglCreatePlatformWindowSurface, eglCreateWindowSurface:

   "If config does not support rendering to windows (the EGL_SURFACE_TYPE
   attribute does not contain EGL_WINDOW_BIT ), an EGL_BAD_MATCH error is
   generated."

for eglCreatePbufferSurface:

   "If config does not support pbuffers, an EGL_BAD_MATCH error is
   generated."

for eglCreatePlatformPixmapSurface, eglCreatePixmapSurface:

   "If config does not support rendering to pixmaps (the EGL_SURFACE_TYPE
   attribute does not contain EGL_PIXMAP_BIT ), an EGL_BAD_MATCH error is
   generated."

Fixes following dEQP test:

   dEQP-EGL.functional.negative_api.create_pbuffer_surface
