Unlike the immDrawPixelsTexTiled functions, this doesn't do tiled drawing, but draws into a full texture.

Use the currently bound shader.

Use immDrawPixelsTexSetup to bind the shader you want before calling #immDrawPixelsTex.

If using a special shader double check it uses the same attributes "pos" "texCoord" and uniform "image".

If color is NULL then use white by default

Unless state->do_shader_unbind is explicitly set to false, the shader is unbound when finished.

#immDrawPixelsTex - Functions like a limited #glDrawPixels, but actually draws the image using textures, which can be tremendously faster on low-end cards, and also avoids problems with the raster position being clipped when off-screen. Pixel unpacking parameters and the #glPixelZoom values are not respected.

Attention: Use immDrawPixelsTexSetup before calling this function.; This routine makes many assumptions: the rect data is expected to be in RGBA byte or float format, and the model-view and projection matrices are assumed to define a 1-to-1 mapping to screen space.
