Konstantin 75f56b7923 glamor: check BPP by render_format.
Check actual BPP by render_format in upload_boxes, not by drawable BPP.

It is required when we used different BPP formats for storing and
rendering (for example, in the case of UYVY).

The problem of UYVY size lies inside method of glamor downloading boxes.

When we set GLAMOR_CREATE_FORMAT_CBCR, it actually uses 16-bit GL and
Pixman formats, but before this change in glamor_download_boxes, that
function deduces GL and Pixman formats from BPP, which is wrong in this
case (will be deduced to 32).

When GL and Pixman format BPP is identical to drawable BPP, this change
does nothing, but when it is different - it will prioritize Pixman
format, not the format deduced from BPP.

Enrico Weigelt, metux IT consult c55ddd072b treewide: replace xnfalloc() calls to XNFalloc()
This has been nothing but an alias for two decades now (somewhere in R6.6),
so there doesn't seem to be any practical need for this indirection.

The macro still needs to remain, as long as (external) drivers still using it.

Michel Dänzer 3e044b1e64 glamor: Add and use glamor_drawable_effective_depth helper
Consider the following window hierarchy, from ancestors to descendants:

 A
 |
 B
 |
 C

If both A & C have depth 32, but B has depth 24, C must effectively
behave as if it had depth 24, even if its backing pixmap has depth 32
as well.

Fixes the xmag issue described in the GitLab issue below.

Michel Dänzer 5371690891 glamor: Fix up alpha channel if needed in glamor_upload_boxes
It's needed for a depth 24 window backed by a depth 32 pixmap, to make
sure the window's pixels sample alpha as 1.0.

v2:
* Make sure glamor_finish_access doesn't pass in a NULL pointer.

Eric Anholt 8702c938b3 glamor: Introduce a central place for our pixmap format/type handling.
We had various helper functions trying to come up with the
internalformat/format/type/render formats for pixmaps, and it's much
nicer to just detect what those should be once at startup.  This gives
us a chance to do the right thing for GLES.

It also, notably, fixes our format/type for depth 15 and 16 setup for
desktop GL, so that we actually allocate 16bpp (GL_RGB/565) on most
drivers instead of 32bpp (GL_RGB/UBYTE).

GLES still has regressions over desktop (2 regressions in llvmpipe
XTS, many in rendercheck), but I think this is a good baseline.

Eric Anholt 34485be256 glamor: Stop trying to store the pixmap's "format" in glamor_pixmap_fbo.
"format" is a bit of a confused term (internalformat vs GL format),
and all we really needed was "is this GL_RED?"

Keith Packard 181a4bd0cc glamor: Preserve GL_RED bits in R channel when destination is GL_RED [v2]
A1 and A8 pixmaps are usually stored in the Red channel to conform
with more recent GL versions. When using these pixmaps as mask values,
that works great. When using these pixmaps as source values, then the
value we want depends on what the destination looks like.

For RGBA or RGB destinations, then we want to use the Red channel
for A values and leave RGB all set to zero.

For A destinations, then we want to leave the R values in the Red
channel so that they end up in the Red channel of the output.

This patch adds a helper function, glamor_bind_texture, which performs
the glBindTexture call along with setting the swizzle parameter
correctly for the Red channel. The swizzle parameter for the Alpha
channel doesn't depend on the destination as it's safe to leave it
always swizzled from the Red channel.

This fixes incorrect rendering in firefox for this page:

while not breaking rendering for this page:

v2: Add change accidentally left in patch for missing
    glDisable(GL_COLOR_LOGIC_OP).

Eric Anholt 07f0d90e4a glamor: Simplify the pixmap box looping.
We had a double loop across h and w, and passed the current x and y
out to callers who then used w to multiply/add to an index.  Instead,
just single loop across w * h.

Keith Packard e6754dcb59 glamor: Use GL_RED instead of GL_ALPHA if we have texture_swizzle (v3)
GL_RED is supported by core profiles while GL_ALPHA is not; use GL_RED
for one channel objects (depth 1 to 8), and then swizzle them into the
alpha channel when used as a mask.

[airlied: updated to master, add swizzle to composited glyphs and xv paths]

v2: consolidate setting swizzle into the texture creation code, it
    should work fine there. Handle swizzle when setting color as well.
v3: Fix drawing to a8 with Render (changes by anholt, reviewed by airlied).
