Robert Bragg 6f480c7530 texture: remove _cogl_texture_prepare_for_upload ... This removes the gl centric _cogl_texture_prepare_for_upload api from cogl-texture.c and instead adds a _cogl_bitmap_convert_for_upload() api which everything now uses instead. GL specific code that needed the gl internal/format/type enums returned by _cogl_texture_prepare_for_upload now use ->pixel_format_to_gl directly. Since there was a special case optimization in cogl_texture_new_from_file that aimed to avoid copying the temporary bitmap that's created for the given file and allow conversions to happen in-place the new _cogl_bitmap_convert_for_upload() api supports converting in place depending on a 'can_convert_in_place' argument. This ability to convert bitmaps in-place has been integrated across the different components as appropriate. In updating cogl-texture-2d-sliced.c this was able to remove a number of other GL specific parts to how spans are setup.
