ba5bf50d5f gl: add and use gst_gl_internal_format_rgba
Previously when compiling GstGL with both GL and GLES2,
GL_RGBA8 was picked from GL/gl.h. But a clash may happen at
runtime when one is selecting GLES2.

gst_gl_internal_format_rgba allows to check at runtime
if it should use GL_RGBA or GL_RGBA8.

ba5130fe01 glmemory: properly detect (hopefully) the correct ext_rg/arb_rg variant
GL_EXT_texture_rg is only valid for GLES2. GLES3 uses similar wording to
the GL_ARB_texture_rg which requires a sized internal format that the
GL_EXT_texture_rg does not require.

17084a4608 glmemory: remove uneeded unref
The call to _gl_mem_alloc_data will unref and NULLify 'dest' for us.

48f8b5b46b glmemory: fix the slight difference between EXT_rg and ARB_rg
GL_EXT_texture_rg doesn't take sized formats for the internalformat
parameter of TexImage* but GL_ARB_texture_rg and GL(ES)3 do.

04377cfc5e glmemory: Support offset when downloading
Make sure we support offset and video alignment when downloading too.
This is currently not used (plane_start is always 0), but it makes
the code correct if we want to use that later.

5f547c5600 gl: initial support for texture targets other than GL_TEXTURE_2D
Make GstGLMemory hold the texture target (tex_target) the texture it represents
(tex_id) is bound to. Modify gst_gl_memory_wrapped_texture and
gst_gl_download_perform_with_data to take the texture target as an argument.

This change is needed to support wrapping textures created outside libgstgl,
which might be bound to a target other than GL_TEXTURE_2D. For example on OSX
textures coming from VideoToolbox have target GL_TEXTURE_RECTANGLE.

With this change we still keep (and sometimes imply) GL_TEXTURE_2D as the
target of textures created with libgstgl.

da3ae06cd1 glmemory: Handle upload/download flags from map
Problem was that if buffer was mapped READWRITE (state of buffers from
libav right now), mapping it READ/GL will not upload. This is because the
flag is only set when the buffer is unmapped. We can fix this by setting
the flags in map. This result in already mapped buffer that get mapped
to be read in GL will be uploaded. The problem is that if the write
mapper makes modification afterward, the modification will never get
uploaded.

acb38a2a79 glmemory: use the plane offsets to compute the size of the data pointer
Certain elements expect that there be a certain number of lines
that they can write into.  e.g. for odd heights, I420, YV12, NV12,
NV21 (and others) Y lines are expected to have exactly twice the
number of U/UV lines.

2da979831e gl/upload: switch the 'master' texture for YUY2, UYVY
From d4bcef3204 on, using a RGBA
texture to hold the data causes the glmemory to have half width
and a scaling of [2, 1].  Using a LA texture solves this problem
however cannot be attached to the framebuffer for copying into
a RGBA texture.  Which will be solved by moving to EXT_texture_rg.

d4bcef3204 glmemory: Fix handling of stride with alignement larger then 8
Setting a scaled factor for X coordinate is not enough as the indexer
will still think stride is shorter and will not fully skip it. Instead,
update width, so the lines are as expected. Combined with the scale, it
will hide the cropped portion.
