* mesa: Remove _mesa_pack_rgba_span_float and tmp_pack.hIago Toral Quiroga2015-01-121-8/+0
| | | | | | | | | | _mesa_pack_rgba_span_float was the last of the color span functions and we have replaced all calls to it with calls to _mesa_format_convert, so we can remove it together with tmp_pack.h which was used to generate the pack functions for multiple types that were used from the various color span functions that have been removed.

* mesa: Replace _mesa_unpack_bitmap with _mesa_unpack_image()Eduardo Lima Mitev2015-01-121-4/+0
| | | | | | | | | | | | | | | | | | _mesa_unpack_bitmap() was introduced by commit 02b801c to handle the case when data is stored in PBO by display lists, in the context of this bug: Incorrect pixels read back if draw bitmap texture through Display list https://bugs.freedesktop.org/show_bug.cgi?id=10370 Since _mesa_unpack_image() already handles the case of GL_BITMAP, this patch removes _mesa_unpack_bitmap() and makes affected calls go through _mesa_unapck_image() instead. The sample test attached to the original bug report passes with this change and there are no piglit regressions.

* mesa: Add helpers to extract GL_COLOR_INDEX to RGBA float/ubyteIago Toral Quiroga2015-01-121-0/+14
| | | | | | | | | | | | | | | | | | | | | We only use _mesa_make_temp_ubyte_image in texstore.c to convert GL_COLOR_INDEX to RGBA, but this helper does more stuff than this. All uses of this helper can be replaced with calls to _mesa_format_convert except for this GL_COLOR_INDEX conversion. This patch extracts the GL_COLOR_INDEX to RGBA logic to a separate helper so we can use that instead from texstore.c. In future patches we will replace all remaining calls to _mesa_make_temp_ubyte_image in the repository (related to compressed formats) with calls to _mesa_format_convert so we can remove _mesa_make_temp_ubyte_image and related functions. v2: - Remove ‘for’ loop initial declaration. They are only allowed in C99 or C11 mode. Reviewed-by: Jason Ekstrand <jason.ekstrand@intel.com>
* mesa: Add RGBA to Luminance conversion helpersIago Toral Quiroga2015-01-121-0/+10
| | | | | | | | | | | | | | | | | | For glReadPixels with a Luminance destination format we compute luminance values from RGBA as L=R+G+B. This, however, requires ad-hoc implementation, since pack/unpack functions or _mesa_swizzle_and_convert won't do this (and thus, neither will _mesa_format_convert). This patch adds helpers to do this computation so they can be used to support conversion to luminance formats. The current implementation of glReadPixels does this computation as part of the span functions in pack.c (see _mesa_pack_rgba_span_float), that do this together with other things like type conversion, etc. We do not want to use these functions but use _mesa_format_convert instead (later patches will remove the color span functions), so we need to extract this functionality as helpers.

| | | | | | | | | | | Rename _mesa_pack_rgba_span_int to _mesa_pack_rgba_span_from_uints. Add _mesa_pack_rgba_span_from_ints.
